Up Topic Welding Industry / Inspection & Qualification / D1.1 vs D1.6 qualification
- - By aglover Date 04-06-2018 14:55
Good Morning all.
I don't have a copy of D1.6 in front of me, but I am wondering about the similarities/ differences in qualification of wps and wpq. as compared to D1.1
I have a customer with a stainless job coming up and I am just trying to do some prep work.
Any advice is appreciated

The two are pretty much the same in context. A whole host of prequalified joints, alloys, and fillers are available and prequalified processes that include GTAW which is not the case with D1.1. Preqaulified thickness are .062" and up just like D1.1.

Although I purchase SWPSs from the bookstore for my D17.1 work,  and apply them to my D1.6 requirements. My customers don't get the prequalified business and feel more comfortable with official documentation.
