Dear Vijay,
Please refer to QW-403.5 of ASME Sec IX.
It states " When base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of these two P-Number Group Numbers to themselves as well as to each other using the variables qualified."
Hope this helps.
Regards,
Sadique

As per SEC IX, any combination of P1, G1 materials can be welded in any combination to P2, G2, provided Impact test requirements are fulfilled.
