After i remove the cap`s, my intention it´s cut off the HAZ of the P91 base metal, re-weld for the final components, PWHT and perform a hardness test. These welds will be Golden welds. My question is: following this procedure which will be the better choice for the welding material: P91, P22 or...
I need to Weld some temporay cap`s in Cs to P)1, just for Hydro Test purpose. I known that the temperatura of PWHT of the two materials are different and it´s not recommended this type of joint, but since it´s a temporary Weld that will be cut there are any suggestions?
Thanks in advance
