Re: [MW:28288] Can I use WPS/PQR P NO-1, Group NO-1 (PLATE) to P NO-1, Group NO-2 (PLATE) for welding of ASTM A333 Gr.6 (P No: 1, Group No: 1) to ASTM A350 Gr.LF2 CL.1 (P No: 1, Group No: 2) ?

Hi Please check your query,

You are saying "Can I use WPS/PQR P NO-1, Group  NO-1 (PLATE) to P NO-1, Group NO-2 (PLATE) " if your PQR is P1 G1 to P1 G2, then you can use this PQR for subject application with impact testing.

If your PQR is P1 G1 to P1 G1, then this PQR cannot be supported for welding the subject application.
