PWHT is determined by the thickness of the material. Depending on how thick the material is will determine if Post weld heat treat is needed. To refer you to a certain code without knowing the code of Construction would only be guessing. There is more caveats involved, but without knowing more information, this is as far as I can go. Refer to the correct code of construction for the fabrication involved.
