[MW:11264] COMBINATION OF 2 PQR IN ONE WPS

Dear All,

I have to weld 40 mm thk ss 304 plate to be welded with root GTAW and
subsequent run by SMAW. I have 2 WPS,one WPS GTAW + SMAW thickness
range qualified is 1.6 to 12 mm and another procedure qualified 5 mm
to 50 mm with back gouging.

My doubt is can i make one wps supporting with these 2 Procedure
Root with GTAW and subsequent run with SMAW so i can carry out the
welding with GTA + SMAW 40 mm thk without further procedure
qualification.

Thanks & Regards.
Manoj
