I am making prequalified joint packages for companies and I have them all done except a few of them don't have pass and layer sequences in the WPDS, so I'm wondering if it is a prequalified joint, does it need a pass and layer sequence in the WPDS and also if it does where do I find them?

I am not sure of any code requirement that would require a pass and layer sequence however that doesn't mean it's not necessary or a good idea. However, if it were, it would be driven by the company doing the welding and they would provide that information.
