Question: What welding tasks are minimum required to apply for the manufacturing qualification for Class D1 and D2 pressure vessels? The product materials are Fe1-1, Fe1-2, and Fe-8-1. Thank you!

I don’t quite understand it, but I think it has something to do with your product structure as well! For example, if you only make containers, or if you make both containers and heat exchangers, those would be different, right?

At least 6 certified welders are required, with the welding methods to include SMAW (for plates and pipes), GTAW (for pipes), and SAW
