A Weld: a localized coalescence of metals or

nonmetals roduced either b heatin the

materials to the welding temperature, with

or without the application of pressure, or

by the appl cat on o pressure alone andwith or without the use of filler material.

A Joint: A junction of members or the edge of

members which are to be ointed or havebeen joined

tee joint (T): a joint between two members located

approximately at right angles to each other

butt joint: a joint between two members aligned

approx ma e y n e same p ane.

QW-403.11 Base metals specified in the WPS shall be

qualified by a procedure qualification test which wasmade using base metals in accordance with QW-424.

QW-424.1 Base metals are assigned P-Number in

table QW/QB-422; metals that do not appear in tableQW/QB- 422 are considered to be unassigned metals

except as otherwise defined for base metals having the

identified in the WPS and on the PQR by specification,

t e and rade or b chemical anal sis and mechanical

properties. The minimum tensile strength shall be de-

fined by the organization which specified the unassignedmetal if the tensile strength of that metal is not defined by

the material specification.

QW-403.8 A change in base metal thickness beyond

the range qualified in QW-451, except as otherwise permitted by QW-202.4(b).

QW-403.9 For single-pass or multipass welding in

which any pass is greater than. 1/2 in. (13 mm) thick,an increase in base metal thickness beyond 1.1 times

that of the qualification test coupon.

QW-403.7 For the multipass processes of shielded

metal-are, submerged-arc, gas tungsten-are, and gasmetal-arc, the maximum thickness qualified for 1 1/2 in.

(38 mm) and over thickness T of the test coupon of QW-

QW-451.1. For thicknesses greater than 8 in. (200 mm),

the maximum thicknesses of base metal and

deposited weld metal qualified is 1.33T or l.33t , as

applicable.

QW-403.5 Welding procedure qualifications shall be made using:

(a) The same base metal (including type and grade) to be used in production welding; or

(b) For ferrous material, a base metal listed in the same P-Number and Group Number (seeQW/QB-422) as the base metal to be used in production welding; or

(c) For nonferrous material, a base metal listed in the same P-Number and Group Number(see QW/QB-422) as the base metal to be used in production welding.

For ferrous material in QW/QB-422, a procedure qualification shall be made for each P- Number and Group Number combination of base metals, even though procedure qualification tests

- . 422, a procedure qualification shall be made for each P-Number and Group Number combination

of base metals, even though procedure qualification tests have been made for each of the two base metals welded to itself. If, however the procedure specification for welding the combinationof base metals specifies the same essential variables, including electrode or filler metal, as both

, , ,the procedure specification for welding the combination of base metals is also qualified. Inaddition, when base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of those two P-Number Group

Numbers to themselves as well as to each other using the variables qualified.

- by other Sections.

QW-403.6 The minimum base metal thickness quali-

fied is the thickness of the test coupon T or 5/8 in.(16 mm), whichever is less. However, where T is less

than 1/4 in. (6 mm), the minimum thickness qualified

qualified with a PWHT above the upper transformation

tem erature or when an austenitic material is solution

annealed after welding.

Question (1): A test coupon is prepared as follows: A

1.75 in. plate is welded to 1.75 in. plate with 1 in. thickweld. Per QW-451.l, is 8 in. the maximum thickness

range of base metal qualified?

Reply (1): Yes, except that further limits or exceptions

may app y as s a e n o es an o - . .

Question (1): A 50 mm thick test plate done for a weld

procedure by FCAW is welded full thickness andreceives X-ray examination and mechanical tests,
