Hi all,

I did a procedure qualification with a 4" pipe and 150 mm plate in 5F position, as per ASME Sec IX QW-451.3 he is qualified to weld all base metal thickness and all diameters.

But for WPQT, he is qualified only for 73 mm and above pipes, does that mean i have to make another performance test for 1/2" and 1" pipes separate are is he qualified to do all size of pipes.

Kindly Clarify.

Regards,

Saravanan S.
