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. 2. 3. 4.

Reduce repair costs Prevent trouble Reduce downtimes, and 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 One Copy: Hitachi (Tokyo)

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

1.

j: Total height of insufficient fusion A: Specified root face

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.

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.). 2) It is acceptable when h is not more than root 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.

INSPECTION PROCEDURE 4.

1. Inspect with a probe.

Print out the input echo data.

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

5. Affix the echo data printout on the inspection Sheet. (Refer to next page.)

2. Detect flaw on the CRT using echo. Flaw wave

3. Touch the max. value point of echo wave on the CRT with a touch pen to input echo data.

6. Judgement

How to fill out the Judgement Sheets Rating 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.

6

Not Acceptable

•

Flaw Size

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.

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.

h: Echo height w (X): Beam distance y (PFD): Probe flaw distance de: Flaw depth H: Flaw height I: Flaw length

Probe

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) 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).

Crack

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

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

3

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.
