[MW:25376] Welding vessel saddles after PWHT

A 100 mm thick and 2.5 meter diameter approximately 10 meter long Carbon steel vessel is being proposed to be PWHT'd with welded wrapper plates on it at saddle locations, so that the saddles may be welded on these wrapper plates after PWHT. This will facilitate turning the vessel on its axis on the manipulator to do extensive internal work involving austenitic SS. Request to share similar experience and precautions to be exercised, so that welding the saddles after PWHT on the wrappers do not induce significant stresses on the vessel. Also references in ASME code or other international codes that allow saddles to be welded similarly after PWHT would be useful.
