Re: [MW:23621] Regarding RT before or after PWHT

Dear ,

Pwht is most important after welding but not for the all line .
Why because we have to identify the changes occur during welding and ...so on so many reasons.

Dear Sir,

As we all aware that PWHT and RT both are different in nature, in general we perform RT after PWHT(Where PWHT is required to be perform after welding). 

However it is not written anywhere that RT is to be performed after PWHT only.

My question now is , can we perform RT first and then go for PWHT? will it be acceptable ????.

I have seen many client inspectors asked contractors to perform PWHT first then RT whereas their specifications does not say anything in this regard.

All experts are requested to throw light on the subject. Documented proof/literature , if any, to support this will be higly appreciable.

regards,

Ajay
