I THINK FROM ONE PQR WE CAN GENERATE AN MANY WPS BASED ON NON ESSENTIAL VARIABLES.
-- BUT THE MATTER OF THE CHANGE IN PROCESS IN WPS IS ESSENTIAL VARIABLE ,NEED TO QUALIFY AN WPS WITH REQUIRED THICKNESS .ITO HAVE NEW CHANGES YOUR HARDNESS OF THE SPECIMEN TOO.
BETTER TO HAVE AN PQR WITH YOUR REQUIRED THICKNESS & PROCESS.

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
