[MW:25065] PWHT confirmation

Hi experts,

Contractors carried out the PWHT and graphs available with correct data's.  Due to urgency the contractor has painted and erected. It is CS material.
Now the owner rejected the reports and asking for PWHT again.

Please send me your best answer  if the PWHT is carried again , whether it will affect the welding and material properties and how to prove that PWHT  has been carried out.  How many times the PWHT could be carried out repeatedly.

Please send your replies.

Thanking you.

With Regards,

Muthu Barathi P.
