Re: [MW:6610] Welding procedure Thickness range qualification

Hi

In ASME Sec IX, QW 403.6 and QW 403.8 are welding variables to be referred for PQR.

For Welder Performance qualification thickness of weld metal qualified, please refer QW-452.1(b).

Regards

referring QW 403.8 thats tells tat refer QW 451.1.

but wats QW 403.6 says? If we refer QW 451.1 is correct or not?



If we see welding variables QW 403.8 is essential variable & QW 403.6

is supplementry variables. wat SEC IX says
