The company I'm working for just got qualified to D1.1 (WSP, PQR, and WQTR).
What do I need to do to be able to use these to qualify to D17.1 Class C?
Do I need to have the CWI that qualified us, to issue new WQTR (Welder Qualification Test Record) and reference the WPS used to qualify to D1.1 and change the conformance statement on the bottom to AWS D17.1/D17.1M:2010, Class C?
TIA
There is no Class C in D1.1.
Someone is blowing smoke up your you know what. If the CWI told you that he qualified you to Class C, you need to find a CWI that knows what he's doing. The one you are using doesn't.

Welder perfromance qualification for Class C D17.1 welds is exactly the same as welder performance qualification testing for Classes A and B.... Which means all tests are tested to Class A quality. Furthermore this means individual PQR's and only when those are completed, conduct welder performance qualification testing...for every alloy, thickness and joint configuration that D17 calls for.
If your D1.1 PQR's match each and every essencial aspect of D17 PQR requirements than maybe you can get some traction.... But it's doubtful...
Not much low carbon steel in the aerospace industry.
Class "C" in D17 is *strictly* targeted to componant criticality.... NOT to welder performance qualification testing.
Look at the D17 references to PQR testing to AWS B2.1 and if your D1.1 PQR's are in line exactly you may have some traction...
Ground support equipment?
