Welding on impact tested (PWHT) vessel without PWHT
Welding on impact tested (PWHT) vessel without PWHT
(OP)
Hi!!
I want to weld a non pressure part (thickness 10mm) to an impact tested vessel of thickness 60mm (P1G2)in service having originally undergone PWHT. Can I weld it without PWHT. What sort of procedure qualification will be required for this.
Regards
