Dear Experts,
We had qualification with GTAW and SMAW (manual process) on 1.5" thick test coupon . to prepare build up welding procedure . our test coupon got Post weld heat treatment at 1150°F for 4 hours ( without solution annealing ) .
Test got failed at the first step for side bend ( see attached picture ).
I`m looking for a reason or reasons of this failure .
Do you think the reason should came from , not perform solution annealing on the test coupon ? or something else should be reason !
Cheers,
DW
