Welding procedure qualification

2021-10-20View Original

Thread Content

Xiaobai is seeking advice: I already have the welding procedure qualification for A333Gr3 low-temperature steel. Now, I need to weld pipes made of A333Gr.6; do I need to conduct another welding procedure qualification and issue a new report, or can A333Gr.3 be used instead?

In ASME standards, A333 Gr3 P-NO. 9B, Gr NO.1, A333 Gr6 P-NO.1, Gr NO.1 – changing the P-NO. is an important factor! To be re-evaluated

Why was my request for help also subject to a mute?

No, it’s posting normally. Do you have the key?
