Re: [MW:14665] Impact WPS P1G1 to P1G1 &P1G2 to P1G2 Qualified P1G1 to P1G2 with impact ?

As per QW-403;

"If, however, two or more qualification records have the same essential and supplementary essential variables, except that the base metals are assigned to different Group Numbers within the same P-Number, then the combination of base metals is also qualified. In addition, when base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of those two P-Number Group Numbers to themselves as well as to each other using the variables qualified."

So the answer of Q1 is "No" and Q2 is "Yes".
