INTRODUCTION

We have already introduced the "EX5600-6 Recommended Preventive Service program" to our customers to

promote good preventive service for the EX5600-6 in the field.

However, to effectively check for various kinds of cracks on welded structures like the Front Attachment Main and

Track Frame etc., periodical examination using an Ultrasonic Flaw Detector is indispensable.

This “Inspection sheet” is provided for easy checking of the condition of these structures on the EX5600-6 by

using our portable ultrasonic instrument series, the “HITACHI UT SERIES”. By executing periodical inspection

with the UT, an appropriate maintenance time can be recommended to your customer before the occurrence of a

lengthy downtime caused by increased cracks.

We believe that you will be able to:

1. Reduce repair costs

2. Prevent trouble

3. Reduce downtimes, and

4. Extend machine life

DISTRIBUTION OF THE INSPECTION SHEET

1. Distribute copies of the inspection sheet onto

which echo data printout is affixed, after

making judgement, as described below.

2. Make two copies of each inspection sheet.

3. Send one of the two copies to Hitachi (L/O,

Representative), and the other to Hitachi

(Tokyo).

One Copy: L/O, Representative

DEFINITION OF THE DEFECT LENGTH IN ULTRA-SONIC TESTING

NOTE: Defect is here defined as that, although varied slightly with welding technique, to be judged acceptable

from the stand point of welding structure.

H: Defect height

L: Defect length

P: Center-to-center distance between defects

j: Total height of insufficient fusion

A: Specified root face

1. Welding with complete fusion (Fig. 1)

1) H:

2 mm (0.08 in.) or less is acceptable.

2) L:

40 mm (1.6 in.) or less is acceptable.

P:

Although the H and L of defect are acceptable

as stated above, center-to center distance

between defects shall be 200 mm (7.87 in.) or

more.

NOTE: No defect is allowed in the range of

50 mm (2.1 in.) on each side of

butt-weld joint.

3) If defect exceeds the above-mentioned limit, it

shall be rejected.

2. Single groove welding with insufficient fusion (Fig. 4)

1) It is acceptable when h is not more than root

face A + 1 mm (0.04 in.) or within A -5 mm (0.2

in.).


face A + 2 mm (0.08 in.), provided that L is 150

mm (5.9 in.) or less, and P is 200 mm (7.9 in.)

or more.

3) If root face A exceeds 2 mm (0.08 in.), it shall

be rejected.

3. Double groove welding with

insufficient fusion (Fig. 6)


face A + 2 mm (0.08 in.) or -5 mm (0.2 in.).


face A + 2.5 mm (0.1 in.), that L is 150 mm (5.9

in.) or less, and P is 200 mm (7.9 in.) or more.

3) If root face A exceeds 2.5 mm (0.1 in.), it shall

be rejected.

4. Other

For welded structures other than the

above-mentioned (1), (2) and (3), it is acceptable

that H is not more than root face A + 1 mm (0.04

in.).

INSPECTION PROCEDURE

1. Inspect with a probe.

2. Detect flaw on the CRT using echo.

3. Touch the max. value point of echo wave on the

CRT with a touch pen to input echo data.

4. Print out the input echo data.

5. Affix the echo data printout on the inspection

Sheet. (Refer to next page.)

6. Judgement

How to fill out the Judgement Sheets

• Wire Acceptable when it is judged that there is no flaw.

• Write Not Acceptable when there is flaw, and add one of

I to IV according to flaw levels listed in the right table.

Rating Flaw Size

Not

Acc

ble

I Flaw height is 5% or less of plate thickness.

II Flaw height is 5% to 10% of plate thickness.

III Flaw height is 10% to 30% of plate thickness.

IV Flaw height is 30% or more of plate thickness.

Positions for the inspection with a probe are two points on both sides and one point on the center of the welding structure.

Use of distance correction method and tip echo method for angle beam ultrasonic testing (How to affix echo data slips to the Inspection Sheet)

1) Check whether any defect (crack) is present or

not at the weld by the distance correction

method. At this time, flow echo in excess of

0% in the CRT graticule, when scanned with

the specified working sensitivity (STB-A3 ø4 x

4 - IS 50%) shall be evaluated. Also, record

the flaw lengths at the same time.

2) For flaw defection portion where the flaw is

detected by the distance correction method,

determine and record the flaw height (H) by

crack tip echo method. If no flaws are

detected by the distance correction method,

then crack tip echo method need not be used.

EVALUATION OF DEFECT HEIGHT (H) BY DISTANCE CORRECTION TECHNIQUE AT INTERNAL BULKHEAD

Pattern No.

Anticipated crack patter and testing direction Testing procedure and crack evaluation

1 (1) It is acceptable that no flaw echo appears when scanning is made from sides A, B, C and D, using angle probe (2.25Z10 x 18A70).

(2) If flaw echo appears, determine defect height (H) by tip echo technique.

2 (3) Internal defect and open surface crack:

Pattern 1: Sides A & B — Internal 1 defect Sides C & D — Open surface crack When root face is 5 mm or less, All of A, B, C and D show internal defects.

Pattern 2: Sides A & B — Open surface crack Sides C & D — Internal defect

Pattern 3: Sides A & C — Internal defect Sides B & D — Open surface crack When root face is 5 mm or less, All of A, B, C and D are internal defects.

Pattern 4: Sides A & C — Internal defect Sides B & D — Open surface crack

NOTE: If the position of the defect is not clear or when judgement is impossible, defects are judgement to be internal ones.
