BY ASME Sec IX for Welder Thickness range qualification, I am
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
For welder thickness range qualification wat we have to refer? either
403.8 or403.6 ?
