Re: [MW:25109] PWHT

According to Section VIII Div. 1 BPVC ASME, you can do some kind of repracion after the PWHT welded, but this only applies to materials P1 and P3 number and for some thicknesses, which clearly defines the code.

After PWHT, if the welding is added , that means  you have to discard residual stresses which occured  due to additional  welding.

Hence, you have to go for Re-PWHT , refernce ASME 31.3
