P # grouping weld question
(OP)
Hey fellas,
If a welder is qualified using a P1 material base metal, is he also qualified to weld on P 45 material? If i'm reading QW-423.1 correctly he is. Thanks a bunch

For instance you can qualify a welder using F4x on P1 test plates to qualify him as a welder on P4x material.

I'm not sure which process your welder will be using, but, QW350 lists the essential variables for welder qualification for the common processes. I suggest you review those applicable to the process you have in mind.
You'll note that QW404.5 is not an essential variable for welder qualification.
