Hi
With this pqr's data
Test coupon thk =0.5"
Process GTAW+SMAW
GT:4mm , SM :8mm
With Impact test
PNO1GR1/2 TO PNO1GR1/2
Code use ... B31.3
the welder can weld branch with od 8" with s20 to 12" header sch30 (pipe)? It needs preparing another pqr ?
Min impact requirement is -46 C or depends on thickness and min design?
