Hey Paul,
How does one support a WPS from multiple PQR's?
NeilHow does one support a WPS from multiple PQR's?
I've used multiple PQR's on a single WPS many, many, many times. When creating a WPS in manufacturing for GMAW I may want the WPS to cover all the electrode diameters (0.035, 0.045, 0.052) and wire feed speed (WFS) ranges that can be run. A typical ER70S-6 WPS could take me 9 PQRs (3 dial. x 3 WFS ranges). That was common for me as a Welding Engineer.
Equally…
When I qualify a single PQR I'll write as many WPS's from it as I can. Example: I qualify a Bevel Groove with a PQR, I'll also write a WPS for a V-Groove, a U- or J-, all the PJP's I can and Fillets. I try to get as much “Bang For My Buck” as I can.

Hi Paul,
Quick addition to this question. Can a CWI write a welding procedure just being a CWI? Or does the company he works for Enginering department have to give him the power to?
