[MW:6806] tests for PQR using R 308 LT1-5 flux cored filler rod

Dear members
 
Can anybody suggest what are the special test requirements for performing PQR on a 6"dia, 8 mm thk. SS 304 pipe using TGX-308L flux cored filler rod for root run.
Subsequent passes are by conventional TIG wire followed by Arc welding.
 
Regards
Hrishi
