Hi guys, like new user of ASME SECTION IX, I'd like to ask you for a few advices.
I should qualify PQR and develop wps for FW of round bar OD16mm (A320LF7) to plate thk 10mm (A516Gr.70), it's for welding runners to baffles and tubsheets for tube bundles of heat exchangers.- also i need to take under consideration secVIII..
350LF2 should be unassigned acc to secIX(equal to 4140 or 42CrMo4 or C1530).
I know how to do it, but i dont know how to characterise this pqr..
Should I qualify PQR as stud weld? Or like standard qualifiction?
I was thinking to go with TIG maual welding, and para QW-192.1.1 say ''The equipment used for stud welding shall be completely automatic ex-cept for manual starting.'' for stud pqr?
Thanks in advance.
