When all other essential variables are same , except PWHT , you have to revise WPS  with PWHT and do further needful in consultation with AI

Hello all,

I have a case for a U stamp vessel , Vessel designed initially with  no PWHT,  hence non PWHT wps applied throughout the production phase,  later the manufacturer converted vessel requirement to PWHT ! Manufacturer justifies since all other patemerts met the requirement othethan  PWHT , they intent to proceed for PWHT ! What's ASME position shall be here ?
