[MW:28287] Re: 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) ?

Hello,

 As Impact testing is required, which become as supplementary essential variable, hence you need a another WPS. For qualifying this WPS (P1 G1 to P1 G2), You have two options,

1. If you have earlier Qualified PQR of P1 G1 to P1 G2, the same may be used as to supporting PQR for the WPS 

2. You need to qualify separate PQR.
