Dear All ;
Base metal between 5 and 30 mm
My design temperature : -46
Impact Test : -46°C 27J
PWHT : 620°C
The materials are SA516 Gr60 and SA516 Gr70.
I want to do a PQR test for the first time but I don't know where to start and how to research.
For example, how many mm thick material, how many mm GTAW and how many mm SAW weld should I use for my PQR to work properly.
