Perform 20% PT to 20% amount of welds of attachments connection plate, result complying with JB4730-2005.5 I Class is acceptable.3、For the welding joint tested with RT or UT, if there is defect, perform welding repair after clearing the defect, and re-test the part with original method until accepted. For the welding joint tested partly, if there is defect, add length of the extended part of the two ends of defect, the added length should be 10% of the welding joint length, and not less than 250mm. if there is still defect, perform 100% test to the welding joint. 4、The repair technology should comply with the welding technology requirement when weld needs repair. The same part on weld should not exceed twice repair, if exceeds, it should be approved by the technology general responsible person of user before repair. The repair times、repair position and repair situation should be recorded in quality certificate. 5、Only the product No. 3MW-01-T shall have test p
