Pro/WELDING

Using Welding

About Welding

With Welding you can:

• Create and modify simple and compound welds in an Assembly. Weld geometry

can be solid or light.

• Prepare edges for welding and create weld notches.

• Hide or display welds in an assembly.

• Define parameters of the welding process.

• Create assembly drawings with welding symbols.

• Obtain both general and specific information about welds, including location,

mass, volume, and size.

• Generate Pro/REPORT tables with rod and weld information

A typical Welding session may include the following steps:

1. Import the reference part into the welding environment by entering Assembly

mode and retrieving or creating an assembly.

2. Define the welding environment by defining welding rods, processes, and

parameters.

3. Determine if you want to weld, prepare edges, or create weld notches, or a

combination of the three.

4. Define the type of weld, edge preparation, or notch to perform on the part or

assembly.

5. Determine the family table configuration. The family table provides the

functionality to create the cut in either the generic or instances of the part and its

assemblies.

6. Determine if you want your weld or feature to contain solid or light geometry.

7. Define the edge preparation cut, notch, or weld dimensions.

8. Set any additional parameters or welding processes.

9. Detail your welding assembly with drawings of welded assemblies and annotate

weld joints.

10. Generate either a bill of materials (BOM) or Pro/REPORT tables with weld

parameters, or both.

To Get Started with Welding

1. Create or open an assembly in Pro/ENGINEER.

Pro/WELDING Help Topic Collection

2

2. Click Applications > Welding. You may see appear in the Right Toolchest

(toolbar to right of graphics window).

3. If you do not see , follow these steps:

a. Click Tools > Customize Screen.

b. In the Categories list, select Weld Feature. Under Commands,

appears.

c. Drag to the Right Toolchest or Top Toolchest.

4. Start to create your welds:

o Click or Insert > Weld to open the WELD DEFINITION dialog box so

you can define the Weld, Edge Preparation, or Weld Notch welding features.

You can define one feature, or a combination of welding features at the

same time.

o Click Tools > Weld to create and define welding rods, processes and

parameters.

Understanding the Welding Interface

About the Welding Interface

The Welding user interface contains the following elements. Refer to Fundamentals

Help for greater detail on the Pro/ENGINEER user interface:

• Menu Commands

Welding menu commands are grouped, and open dialog boxes or submenus for

step-by-step weld creation.

• Welding Dialog Boxes

o Expandable and collapsible dialog boxes sections are indicated by a black

triangle. When you click the triangle, a section expands or collapses.

o Enables you to define attributes of your welding operation by separating

major groupings within a dialog box.

o Enables you to simultaneously create or modify multiple welding features

and feature types.

o Provides dynamic options that update as you make selections.

About the Model Tree with Welding

The Model Tree provides a feature-level visual representation of your welding

project. Each feature you create is chronologically represented in the Model Tree.

Highlights of the Model Tree follow. Refer to Fundamentals Help for greater detail on

the Pro/ENGINEER user interface.

Pro/WELDING

3

Using the Model Tree, you can:

• Make features more visible by highlighting them.

• Reorder features, and ultimately change the project dynamic, by dragging

features to various locations.

• Access a shortcut menu that enables you to create and modify your design. The

shortcut menu may include commands to:

o Edit and edit the definition of welding features.

o Hide or unhide, suppress or resume, welding features to simplify or

accentuate areas of your welding design.

o Meet your design intent quickly by using the Pattern tool to pattern weld

features.

o Obtain information, and create notes about welding features.

o Convert light welding geometry to solid geometry (and vice versa).

o Edit parameters.

You can define which features display and how they display in the Model Tree, by

clicking the Show and Settings tabs.

About Using Layers in Welding

You use layers in a model or a layout as an organizational tool. By associating items

with a layer, you can collectively manipulate features including deleting, reordering,

suppressing, or hiding and unhiding them as necessary.

While there is no specific default layer for welding, you can set a default layer for all

welding features (light and solid) by setting the configuration option def_layer to

layer_weld_feat <layername>, where layername is the name you assign the layer.

For example:

def_layer layer_weld_feat allwelds

Weld features you create after setting this option are automatically added to this

default layer.

You can customize your welding layers, and how they display, by clicking Show >

Layer Tree from the Model Tree.

Creating a Layer for Light Welds Only

You can create a layer for light welds only from the Rule Editor dialog box. Set both

the rules described below:

Look for = Feature

Look by = Feature

Attributes = Type

Look for = Feature

Look by = Feature

Attributes = Type


4

Comparison = is equal to

Category = Welding

Value = Welding Feature or any

other welding type.

Comparison = is not equal to

Category = Miscellaneous

Value = Has Quilts

For more information on rules in layers, see Fundamentals Help.

Displaying Welds

About Displaying Welds

You can control the display of welding features in the graphics window, the Model

tree, the Layer Tree, and in other applications. When working in Welding, you can

make various selections to modify how and when weld features appear.

Displaying Features in the Model Tree

Features, by default, are not visible in the model tree for an Assembly. You must

select Features from the Model Tree Items dialog box (Settings > Model Tree

and select Features). The model tree expands to include all features in the

assembly, including welding features.

Displaying Weld Features in the Layer Tree

Set the configuration option def_layers to layer_weld_feat <layername> to see

weld features in the layer tree. All weld features are automatically included in the

layer.

Hiding and Unhiding Weld Features

You can hide weld features by right-clicking on a weld feature and selecting Hide.

This removes the weld display in the graphics window.

You can also hide the layer containing weld features so all weld features are hidden.

Changing the Default Weld Color

There is a default color for all welds or you can set the color for all welding features

using the configuration option weld_color. All welds created after you set this

configuration will conform to the color you defined. You can also set colors for

individual or multiple welds in your assembly. The new color is also visible in other

applications, such as the Standard application.

Using Welding Icons

Use to quickly access the WELD DEFINITION dialog box. If you do not see this

button after starting the Welding application, you can take steps to position it.

Unique icons identify welding features in the model tree. Some are listed below:

Pro/WELDING

5

• —Solid Fillet Weld

• —Light Fillet Weld

• —Solid Edge Preparation

• —Light Edge Preparation

• —Welding Rod

• —Welding Process

Displaying Light Welds

By default, both solid and light welds are visible in the graphics window. You can

toggle the display of light welds from the Model Display dialog box (View >

Display Settings > Model Display), by selecting or clearing the Weld check box.

When light welds are displayed in applications other than Welding, or when they are

exported and appear in 2D and 3D interfaces such as IGES and STEP, they appear as

thick lines. The thickness of the light weld line distinguishes it from a regular datum

curve.

To Hide or Unhide Welds

You can hide or unhide welds, using the Model Tree, the Layer Tree, or the View

menu.

To Hide or Unhide Welds Using the Model Tree

1. Select the weld you want to hide or unhide and right-click.

2. Select Hide to temporarily turn off the weld display in the graphics window or

Creating Rods, Processes, and Parameters

About Setting Up Welding

Setting up Welding for your designs helps you control your overall welding design

process and to set defaults for common weld elements.

When you set up Welding you can:


10

• Create and assign various welding rods for your design.

• Establish company or industry welding processes to guide and automatically

document your weld creation.

• Maintain consistency in your design by setting welding parameters.

Welding Rods

About Welding Rods

A welding rod, identified in the Model Tree by , provides the welding material

necessary to create a weld bead. A welding rod has a circular cross-section and

attributes, such as density, diameter, and length, which you pre-define.

Within a welding assembly, each welding rod is defined by its name and parameters.

Rod parameters are stored with the model. However, you can use and reuse welding

rods in any of your welding assemblies by storing the rod parameters in a .rod file in

your working directory.

You define and work with welding rods almost exclusively in the WELDING RODS

dialog box. First define (or retrieve) rods for the assembly and then assign a selected

rod to a weld. You can assign the same welding rod to multiple welds. From a weld

feature, you can change a rod assignment from the shortcut menu or edit the weld

feature definition to add or change a rod.

When you delete a rod that was assigned to a weld, you also need to delete the weld

that uses that rod. To avoid having to delete the weld, first unassign the rod and

then delete it.

To Define and Edit Welding Rods

You define and edit welding rods using the WELDING RODS dialog box.

1. Click Tools > Weld > Rod. The WELDING RODS dialog box opens. If you

already defined one or more rods, the rod names are listed in the Rod List and

Welding Processes

About Welding Process Parameters

A welding process is identified in the model tree by . By defining process

parameters you can streamline the creation of welding designs, ensure design

consistency, and save time.

Typically, you define your welding process parameters before you create any welding

features. However, you can assign and unassign welding process parameters at any

time in your design.

With the welding process parameters you can:

• Assign a machine type and indicate when and where to create the welding

feature.

• Specify a specific feed rate.

• Select welding treatments, shapes, backing, and finishes.

• Apply company or industry specifications.

• Establish acceptable rod and root opening lengths.

You can further customize your welding process by assigning optional and user-

defined parameters.

Welding Parameters

About Welding Parameters

Welding parameters automate routine tasks to help streamline your welding design.

You can predefine some common feature geometry to ensure design consistency and

to save time.

Within a welding assembly, each welding parameter is defined by its name and its

type of parameter. Welding parameters are stored with the model, however, you can

use and reuse welding parameters in any of your welding assemblies by storing the

parameters in a .wpr file in your working directory.

You can divide welding parameters into the following categories:

• General—Predefines geometry and establish general welding feature behavior in

your assemblies.

• Report—Predefines and establishes welding data for your welding reports.

• Rod—Creates and controls the behavior of welding rods in your welding

assemblies.

You can further customize your welding assemblies by expanding the parameters

contained in the categories above by creating optional and user defined parameters.

Welding Measurement Parameter


18

A welding measurement parameter is a common user-defined parameter based on a

measurement from the model. First you create a parameter name and give it the

value of measure. Then you define what requires measuring. Alternatively, you can

define the measurement first, and then create the parameter.

Controlling a Weld Cross-Section Parameter Using Relations

Pro/WELDING

23

If you want the X_SECTION_AREA parameter to update whenever geometry changes,

you can specify a relation that causes this parameter to be recalculated

automatically.

Two types of parameters can be used in a relation that you specify for the

X_SECTION_AREA parameter:

• Model dimensions or any dimensions of an existing weld (such as, leg size) in

their symbolic form (such as, d32).

• Measurement parameters.

When you access the Welding Parameters Info window, the relation that you entered

for the X_SECTION_AREA parameter is listed in the table. Values of the measurement

parameters can be viewed in the Model Info window.

Method 1: Using the Evaluate Feature

1. Create a weld and specify the initial value for the X_SECTION_AREA parameter.

2. Create an assembly surface feature using the Flat option with the profile of the

surface corresponding to the cross-section of the weld.

Creating a Surface Based on the Weld’s Cross-Section

`

3. Create an assembly Evaluate feature, measuring the area of this cross-sectional

quilt. Specify the name of the Evaluate feature (such as, X_SECTION_AREA).

4. Create an assembly relation which relates the measurement of the surface

feature and the X_SECTION_AREA parameter of the weld. (Obtain the internal ID

of the weld using Info/Feat Info.) Enter the following relation:

X_SECTION_AREA:fid_weld_id = X_SECTION_AREA:fid_evalfeat_id

where:

weld_id - is the internal feature ID of the weld.

evalfeat_id - is the internal ID or the name of the Evaluate feature.

5. Regenerate the model. The system updates the X_SECTION_AREA parameter of

the weld; the volume of the weld updates accordingly.

6. If desired, you can put the flat surface on a layer and blank this layer.

Method 2: Using the CALC_X_SECTION_AREA Parameter

1. When defining a weld, define the X-Section plane in the WELD DEFINITION

dialog box. This creates a parameter CALC_X_SECTION_AREA.


24

2. Create a relation X_SECTION_AREA=CALC_X_SECTION_AREA. When the system

solves this relation, it gives you the updated values for the cross-section area.

Tip: Entering Information in the Welding Parameters Table

To set up a relation between a welding parameter and measurements of some

geometric elements, you enter the following information in the WELD PARAMETERS

dialog box.

1. Enter an equation as a value for the desired parameter.

2. For the measurement parameter used in the relation, enter the following line:

parameter_name measure

where:

parameter_name is the name of the parameter.

For example, you could add the following lines to the table in the WELD

PARAMETERS dialog box:

X_SECTION_AREA a*b/2*1.2

a measure

b measure

Note: The length of a relation is limited to a single line of text and you cannot use

conditional statements.

Creating Welding Features

About Creating Welding Features


28

You define the following Welding features in the WELD DEFINITION dialog box:

Edge Prep (Edge Preparation)—Prepares edges for welding when parts and

assemblies require certain strength.

Weld—Joins metal parts with pressure or an intermediate filler metal with a high

melting point.

Notch—Creates a cut that enables your welds to cross assembly components

without interruption.

You can define one or more Welding features at a time. When defining multiple

features, you can create edge preparations, welds, and notches in a sequential order.

For Weld and Edge Prep features, you can create a single feature (Single), the

same weld on both sides of the metal wall (Symmetrical) or for the weld feature

only, separate welds on both sides of the metal wall (Unsymmetrical). Although

each Welding feature requires a different set of attributes and parameters, there are

some common themes between the three Welding features.

You define the welding environment to accurately create the weld in either the

factory or field. For example, if you are defining a Weld only:

• Select a rod. A rod provides the welding material necessary to create a weld

bead. You can use and reuse welding rods in any of your welding assemblies

• Select the geometry type for the weld. Both solid and light welding features

maintain all the necessary definitions and parameters. You can convert between

solid and light features for manufacturing and design purposes

• Clear or select the Create Family Table Instance check box. Welding features

belong to the assembly, not to the part. This option controls how and where edge

preparations, welds, and notches interact with the Family Table for your

assembly. If you choose to create a family table instance, you can customize the

instance name suffix and set the weld visibility to either the generic part or to

instances of the part and its assemblies. See Fundamentals Help for information

regarding Family Tables.

Creating Curves and Light Welds

When creating a weld, you can select a combination of curves and edges (one

reference after another) when you use the One By One command. When you are in

the Welding application you can insert datum curves and then use a combination of

curves or curves and edges to create a Light weld.

While you are creating a weld, you can insert datum curves, as you do in the

Standard application. The Copy, Paste, Intersect, Project, Wrap, Offset, and Trim

tools are also available in Welding, although they are not available while you are

defining the weld.

About Welding Geometry Types

After deciding the type of Weld or Edge Prep welding feature to create, you must

also decide how to create geometry in your design. You can select to create either

Solid or Light geometry.

Pro/WELDING

29

Solid—Creates and shows the solid

geometry within the design. The Weld or

Edge Prep feature contains all the

necessary data for manufacture and is

represented by solid geometry in the

design.

1.Reference for solid edge preparation.

Light—References existing curves or

edges but has no geometry of its own.

The Weld or Edge Prep feature contains

all the necessary data for manufacture,

but is represented by the geometry it

references (edge, surface). The lack of

solid edge preparation geometry can

significantly reduce the regeneration and

graphic load times for your design.

2.Reference for light edge preparation.

Because light welding features geometry maintain all the necessary edge preparation

and weld parameters, you can quickly convert Light to Solid (and vice versa) for

manufacturing and design purposes. If your are creating a number of welds and edge

preparations in your model, consider creating (and keeping) all the welds and edge

preparations as light geometry and then converting them to solid as needed for

manufacturing.

Note:

• The Welding configuration options weld_edge_prep_instance and

weld_edge_prep_suffix provide the flexibility to customize instance naming

conventions and specify on which models the edge preparation features are

located.

• When using light edge preparations, be sure to note the information for the

Welding mass properties calculation (Info > Welding > Mass). The mass for

light edge preparation is not calculated automatically. Therefore, without user

action, the light edge mass is not considered in Mass calculations.

Preparing Edges

About the Edge Prep Welding Feature

Edge preparation consists of removing material along edges of metal surfaces. You

must prepare edges for welding when parts and assemblies require certain strength.

To achieve full welding penetration, you must cut the edges of the metal. The weld

replaces the removed material and makes a complete bridge between the joining

parts.

The following types of edge preparation are available:


30

—One side root opening —V-groove angle cut

—Bevel-groove angle cut —V-groove angle cut with root

opening

—Both sides root opening —Bevel-groove angle cut with

root opening

Edge preparation is only possible for certain weld types. For example, root opening

preparation is available for Square-Groove, V-Groove, Bevel-Groove, U-Groove, J-

Groove, Flare-V-Groove, and Flare-Bevel-Groove welds. Angle cut preparation is

available for V-Groove and Bevel-Groove welds.

Default Values for Edge Preparation

The WELD DEFINITION dialog box enables you to declare default values for depth,

groove angle, and root opening for weld edge preparation. If a gap exists between

two surfaces, the dimension of the gap is considered in the equation when you

specify root and angle cut measurements.

Examples of Depth, Groove Angle, and Root Opening

1 Groove Angle

2 Depth

3 Root Opening

To Prepare Edges for Welding

You can combine the edge preparation procedure with the procedures for creating

welds and adding notches. You can only prepare edges and create notches if you

simultaneously create a weld.

1. Click or Insert > Weld. The WELD DEFINITION dialog box opens.

2. Under Feature, click the Edge Preparation check box.

Note: You can also create welds and notches simultaneously with the edge

preparation:

o To join metals by applying heat or a filler metal with a high melting point,

or both, click the Weld check box.

o To create an opening (cut) that enables your welds to cross assembly

components without interruption, click both the Weld and Notch check

boxes.

3. Under Combination, define how to create the geometry:

o Single—Creates a single edge preparation.

o Symmetrical—Enables sequential creation of the same edge preparation

on both sides of the part.

o Unsymmetrical—Enables sequential creation of separate edge

preparations on both sides of the part.

4. Click the Environment tab to define the edge preparation characteristics:

o Click the Create Family Table Instance check box to control welds in

part or for family table instances,

o Set the Edge Prep Driven by to control the edge preparation's

dependency in your design,

Click Part to make the edge preparation dependent on the individual part.

Click Assembly to make the edge preparation dependent on the entire

assembly.

o To control the edge preparation geometry in your design, set the Edge

Prep Geom Type:

Click Solid to create the solid geometry within the design.

Click Light to create the edge preparation without the solid geometry.

5. Define the type of edge preparation cut to create and how to offset the contact

surfaces:

o —One side root opening

o —Bevel-groove angle cut

o —Both sides root opening

o —V-groove angle cut

o —Bevel-groove angle cut with root opening

o —V-groove angle cut with root opening

Creating Welds

About the Weld Feature

A weld joins metals by applying heat or a filler metal with a high melting point, or

both. In Welding you create welds from parts opened in assembly mode. Welds are

created in a top-level assembly as an assembly feature. Welds and feature geometry

are represented as quilts with a high level of complexity.

Consider the following about the weld feature:

• A weld feature does not change geometry of welded components. Before you

proceed to welding, make sure components to be welded have appropriate

profiles.

• Adding a weld does not merge referenced components. When you retrieve a

component that was welded in an assembly, its geometry remains the same.

Pro/WELDING

33

• Welds are parametrically defined features. They are associative with the

referenced geometry and can be manipulated as other standard Pro/ENGINEER

features.

• Weld faces are represented in the assembly as quilts. A quilt represents a

patchwork of connected nonsolid surfaces and may consist of a single surface or

a collection of surfaces.

The following weld types are available:

—Fillet —Bevel-Groove or

Butt

—Flare-V-Groove

or Butt

—Square-Groove

or Butt

—U-Groove or Butt —Flare-Bevel-

Groove or Butt

—V-Groove or Butt —J-Groove or Butt —Plug

—Spot

—Slot

Weld Identification

Each weld feature maintains a feature ID, a weld sequence ID, a welding rod,

welding parameters, weld type, and geometric references.

Weld Identification Format Where:

# :Type_of_weld, Rod: Rod_name #— The sequence ID of the weld.

Type_of_weld—The type of weld

(such as, "Fillet Weld").

Rod_name—The name of a rod (such

as, "Steel_001").

Example: 1:Fillet Weld, Rod: Rod1

About Welding References

There are two major steps in the creation of a Weld feature:

1. Define the weld.

2. Specify the weld location.

You define a weld from the WELD DEFINITION dialog box by selecting the weld

feature type (Fillet, Square-Groove, V-Groove etc.), the environment for the weld

feature type (Solid, Light, Intermittent. etc, ) and by adding parameters. Next, you

specify the weld location by referencing weld component geometry, using commands

from the REF OPTIONS and CHAIN menus. Commands available on these menus

during weld creation depend on the weld type you are creating.


34

REF OPTIONS and CHAIN Menu Commands

Commands on the REF OPTIONS menu are as follow. For each command, you must

select at least one reference from each component.

• Chain-Chain—Selects a chain of edges or curves or a combination of the two on

each component. A weld is created by referencing datum curves from the

components to be welded. For each component, specify a datum curve or a chain

of curves using options in the CHAIN menu.

• Chain-Surf—Selects a chain of edges or curves or a combination of the two on

one component, and a surface on the other component. A weld is created by

referencing a chain of edges from one component and continuous surfaces from

the other component.

• Surf-Surf—Selects a surface on each component. A weld is created by

referencing surfaces from two components. For each component, you must

specify continuous surfaces.

Commands on the CHAIN menu are:

• One By One—Collects a combination of edges and curves, one entity at a time.

• Tangnt Chain—Collects tangent edges.

• Curve Chain—Selects and collects curves. To select a chain of curves by picking

a curve from the chain.

• Bndry Chain—Collects one-sided edges belonging to the same surface list.

• Surf Chain—Collects surfaces.

• Intent Chain—Collects edges to capture intent.

Fillet Welds

About Fillet Welds

Creating Welds along the Segmented Trajectory

Pro/ENGINEER calculates the fillet weld trajectory for two adjacent surfaces by

projecting the edge of each surface on the other.

You can weld surfaces in which the weld trajectory is broken into two or more

continuous segments. These cases can be broken down into two classes, as shown in

the following examples:

• Segmented trajectory; one physical weld (Example A)

• Segmented trajectory; multiple physical welds (Example B)

Spot Welds

About Spot Welds

A spot weld is a joint (or weld) between two overlapping pieces of material.

Typically, spot welds are used for sheet metal.

To create spot welds, you reference datum points. You can select existing datum

points or create datum points in the process of routing the weld. There are two

methods of creating a spot weld:

• Define multiple locations for spot welds and create multiple welds in one

operation.

• Create a single spot weld and pattern it using the Pattern command.

The following table shows the key dimensions of the spot weld:

Weld Type Example Key Dimension

Spot

P - Penetration/height

XA - Cross-section area

d1, d2 – Dimensions locating the center of

the spot weld

R - Radius of the spot weld is calculated as

follows:

R = √XA/Π

Spot welds display as circular surfaces. The diameter of the circle is calculated by the

system based on the value of the X_SECTION_AREA parameter entered by you when

defining weld parameters. To modify the size of the spot weld, you need to change

the X_SECTION_AREA parameter. You can set up a relation controlling the area of the

weld.

Adding Weld Notches

About Adding Weld Notches

A weld notch is an opening (cut) that enables your welds to cross assembly

components without interruption. Both the standard and user defined notch shapes

enable you to automate and standardize the weld notches in your design, ensuring

design consistency and saving you time.

You can create single weld notches or you can combine weld notches with edge

preparation and weld features. You can only combine weld notches and edge

preparations if you simultaneously create a weld feature.

You can create a weld notch by manually specifying its individual references

(dimensions, location, orientation, and intersecting parts) or you can automatically

adopt the weld notch references by referencing the weld notch to a solid or

lightweight weld.

Weld notches are oriented using coordinate systems. The x-and y-planes are used to

place the weld notch and the z-axis defines the direction to remove material. This

automatic orientation is accurate. There will be cases where this type of orientation

does not meet your design need. If you need a custom notch orientation, define an

alternative coordinate system and modify the weld notch's orient section.

Multiple intersections of one assembly component part by a single weld notch are not

allowed. To create multiple intersections on the part create several weld notch

features. The first weld notch feature can be created automatically and then you

should create the additional notch features with coordinate systems that define their

placement and orientation on the component part.

Changing Welding Features

About Working with Welding Features

Use Welding functionality described below to help enhance your overall design and

welding process.

• Duplicate welds—To quickly duplicate a single weld, you can use the Pattern

tool, to pattern welds in your design. Spot welds are the most appropriate welds

for Dimension, Direction, Axis, and Fill patterning, however, you can create

Reference patterns for all weld types. See Part Help for information about

patterning.

Note: You can pattern Welds, but you cannot pattern Edge Preparations or Weld

Notches.

• Edit the dimensions and definition of welding features—To better meet

your design intent, you can edit the definition of welding features or edit the

dimensions of welding features. You can also change the number of welds in a

pattern.

• Create design variations—To vary your welding design, you can suppress,

resume, and reorder welding features. Suppressing some welding features can

also reduce the regeneration and graphic load times for your design. If you

rearrange the sequence of regular Pro/ENGINEER features you might need to

reorder the corresponding welding features.

• Reinforce welds—To reinforce your welds or to create both-sides welds within

your design, you can combine weld features. You can separate welds using the

Uncombine command.

• Quickly change geometry types—To change light geometry to solid geometry

(and vice versa) for manufacturing or design purposes, you can convert the

geometry types in your welding design.

About Converting Welding Geometry Types

Because both solid and light edge preparations and welds maintain all the necessary

definitions and parameters, you can convert between solid and light welding features

for manufacturing and design purposes using one of the methods below:

• From the Weld Conversion dialog box, select and convert multiple Weld and

Edge Prep features, along with any dependent features (children) to the opposite

geometry type.

• Select an Edge Prep or Weld feature from the Model Tree and use the shortcut

menu command Convert.

• From the EDGE PREPARATION or <Weld Type> WELD dialog box, select the

Element, Geom Type and change the geometry type of the selected feature.

You can convert solid and light edge preparation geometry types from within parts

and assemblies. When you are working in an assembly with the Standard application

(Application > Standard) and are converting similar weld and edge preparation

features (light weld, light edge preparation), you must convert both features

simultaneously (solid weld, solid edge preparation). When you are working with a

part in the Standard application, you can convert separate types (solid weld, light

edge preparation). However, when you enter the Welding application after making

the conversion in the Standard application, you receive a warning message

suggesting that you manually convert to resolve the discrepancy.

Obtaining Welding Information

About Welding Information

Welding information provides general data about your welding design features,

including the assembly name, weld type, rods, mass properties, and any welding

processes assigned.

You can obtain the following information:

• Overall attributes of welds

• Length of welds and welding rods


62

• Mass of welds and welding rods

• Parameters controlling welds

• Bills of material for welds

It is important to keep your weld information in mind, especially with respect to light

edge preparations and your mass properties calculation. While the light edge

preparations do not display solid geometry in your design, they can have a

significant effect on the design's mass properties measurement.

The length and mass of rods is measured using the following criteria:

• Total rod length is the sum of the lengths of the specified rods. Length is

computed by summing the lengths of the particular rods used by all the welds in

the assembly.

• Total rod mass is the sum of the mass of the specified rods. Mass is computed by

summing the mass of the particular rods used by all the welds in the assembly.

The information produced for general weld information, weld and rod length, weld

and rod mass, and bills of material is written to .dat files in your working directory.

Information Type File Name

General weld information weldinfo.dat

Length of welds weldlengthinfo.dat.#

Length of rods rodlengthinfo.dat.#

Mass of welds weldmassinfo.dat.#

Mass of rods rodmassinfo.dat.#

Bill of Materials weldbominfo.dat.#

To Obtain Welding Information

You can access information about welding features from the Model Tree, Info menu,

or from various dialog boxes within the Welding application. Either the

Pro/ENGINEER browser or the INFORMATION WINDOW opens with the

appropriate information. When the INFORMATION WINDOW opens the text is also

stored in a .dat file and the filename appears at the top of the window. The .dat file

is automatically saved to your working directory or you can click File > Save to save

it to another name or directory.

To Obtain Welding Feature Information from the Model Tree

1. Select the welding feature.

2. Right-click and select Info > Feature. The Pro/ENGINEER browser opens and

Note:

Total rod mass is the sum of the mass of the specified rods. Mass is

computed by summing the mass of the particular rod used by all the welds

in the assembly.

Total rod length is the sum of the lengths of the specified rods. Length is

computed by summing the lengths of the particular rod used by all the

welds in the assembly.

4. If you select BOM, the INFORMATION WINDOW containing BOM (bill of

material) information for the welds in the model opens.

Note: You can also get information about welding rods, processes, and parameters

from the Info menus in the WELDING RODS, WELDING PROCESSES and WELD

PARAMETERS dialog boxes. Click Tools > Welding.

Finite Element Analysis of Welded Assemblies (FEA)

You can perform a Finite Element Analysis (FEA) of an assembly with weld joints

using the same techniques as with other assemblies. A variety of FEA elements can

be used to model weld elements, as for example, bar elements, shell elements, and

contacts.


64

To analyze a FEM model and review the results of analysis, you need licenses for

Pro/MESH and Pro/FEM-POST.

Detailing Welding Assemblies

About Welding Symbols in Drawings

The standard Pro/ENGINEER welding symbol libraries provide general ANSI and ISO

welding symbols. The library symbols are the default symbols. You can easily

customize and create new welding symbols to accommodate any symbol

preferences.

When Pro/ENGINEER places welding symbols in your drawing it only recognizes

welding symbol names stored in the standard Pro/ENGINEER welding symbols

libraries. If you create a new welding symbol, you must use it to replace an existing

symbol in the welding symbols library. As a general rule, it is advisable to redefine

an existing weld symbol.

As you customize your welding symbol you can do any or all of the following:

• Add as many copies of variable texts as you want.

• Change the default values of variable texts.

• Add and delete as many notes and entities as you want and place new ones in

any group (or in no group at all).

• Redefine the cosmetics of existing notes and entities.

• Move the origin position for Left Leader and Right Leader or add other leader

types.

• Add parameters to the symbol definition.

You can label your welding features with either ANSI or ISO weld symbol standards.

The weld_symbol_standard configuration option in the Detail module enables you to

set the symbol support for your drawings.

The following weld symbols are supported in ISO:

• Non-grooved—Fillet, plug, slot, and spot

• Grooved—Square, bevel, v, u, and j

Note: For bevel and v-symbols, if root_open is more than zero, the "steep"

version of the symbol is used. If prep_depth is less than material thickness, the

broad version is used.

To Display Welding Symbols for Existing Welds in a Drawing

With your welding drawing open:

1. Click View > Show and Erase. The Show/Erase dialog box opens.

2. Under TYPE click .

Pro/WELDING

65

3. Under Show By specify where to display the symbols:

o Feature—Shows a symbol for a selected weld feature.

o Feature and View—Shows a symbol for a selected weld in a selected view.

o Part—Shows all symbols in a selected component.

o Part and View—Shows all symbols in a selected view of a selected

component.

o View—Shows all symbols in a selected view.

o Show All—Shows all the symbols in the drawing. Each welding symbol is

displayed only once.

4. Use the Options and Preview tabs to define when and what symbols will

display. After you have set the criteria for your welding symbol display, the

symbols appear in your drawing.

To Redefine a Weld Symbol

Note: Before you start, you must first specify the user’s symbol root directory,

because Pro/ENGINEER will only let you save the redefined weld symbols in or below

it. Later, you can copy the redefined symbols over the old ones in the system

symbols libraries.


1. To place an existing symbol palette in your drawing click Insert > Drawing

Symbol > Symbol Instance Palette. The Symbol Palette dialog box opens.

a. Select a symbol from the dialog box.

b. Place the symbol in your drawing.

c. Repeat as necessary and click Close.

2. To create or redefine an existing weld symbol, click Insert > Drawing Symbol

> Custom. The Custom Drawing Symbol dialog box opens.

a. Define or redefine the symbol.

b. Repeat as necessary and click OK.

Restrictions for Redefining a Weld Symbol

When you are redefining weld symbols, the following restrictions apply:

• All of the groups that existed in the original definition must remain in the new

definition. You cannot add new groups or change the names of existing ones.

• If you add new variable text or change the name of an existing piece of variable

text, the new name must be the same as that of an existing variable text in the

original.

• The height type of the symbol instance must be the same in the new symbol as it

was in the original.


66

• The Left Leader and Right Leader placement types must both exist in the new

weld symbol.

To Replace a Symbol in a System Weld Symbol Library

The system weld-symbol libraries are located in the installation directory path

<install_dir>/symbols/library_syms/weldsymlib. To replace a standard symbol

with one that you have redefined, ask your system administrator to do the following:

1. Move the original (system-supplied) symbol from the system weld library to

another directory or rename it.

2. Copy the new user-redefined symbol into the system weld library.

To Store a Redefined Weld Symbol

You do not have to store a symbol on disk to use it in your current drawing.

However, you must store the symbol on disk for the symbol to be available for other

drawings or other users.


1. Click Format > Symbol Gallery. The SYM GALLERY menu appears.

2. Click Write. The GET SYMBOL menu appears.

3. Click Name. The SYMBOL NAMES menu appears.

4. Click the name of a symbol previously retrieved or VIEW_TEMPLATE_SYMBOL. You

are prompted for a directory.

5. Type the name of the destination directory (offset from the symbol root

directory) and click . The weld symbol is stored.
