Re: [MW:10752] QW -350 WPQ WELDING VARIABLES; P-Number Clarification,,,

Dear Friend,

You are correct that if any welder qualified with P1 material then range of his qualification P1 to P15f, P34, P41 to P49

But at same F-No. also essential variable. By this if any welder qualify in P1 then he cannot weld in P8 (SS 304) because change in F-No. essential variable.

Dear All,

as per ASME sec 9,

For welder qualification,
as per QW -350, P-Numbers are essential variable.
so change in p number needs to requalified.
& G-Number is not an essential variable. its no issues with G-Number.

1) My question is the above said are right or not..?
If any correction. pl let me know...

Q2) & is the welder qualified to weld P1 to P11, P34, P41 to 49.?

Thanks & Regards
