PQR: P.No-1 Gr.1 weld to P.No-1 Gr.2
PQR: P.No-1 Gr.1 weld to P.No-1 Gr.2

Dear Gents,
We have one PQR: P.No 1 Gr.1 weld P.No 1 Gr.2 So Can we write WPS: P.No 1 Gr.1 weld to P.No 1 Gr.1, P.No1 Gr.2 weld to P.No1 Gr.2? Require CVN test, Follow ASME IX

The sample, I use electrode ER70S-6 to weld API 5L X52 (Gr.1) with API 5L X65 (Gr.2).This PQR passed (CVN test both HAZ's, tensile: 460 MPA meet acceptance criteria Gr.1 but not meet acceptance criterial Gr.2 "530MPA"). So We will weld API 5l X65 to API 5L X65 by electrode ER70S-6. This is difficult understand??
