Change the process in Root Pass
Change the process in Root Pass
(OP)
One of major point of inspection of the weld specially in one side welding that may effects on the quality of an existing WPS is root pass.
More over there is only One para. in ASME Sec. IX (QW-200.4) that discused about root pass requirement and it seems that changing of root pass is not essential factor for a WPS.
Is it correct to delete or change the process of the root and it's no needs to peform new PQR?.
