Re: [MW:23748] MT before or after PWHT?

It is like  whether RT to be done before or after PWHT. 

Similar to RT, prefer to do MT also prior to & post PWHT . 

Defects if any can be rectified  prior hand to avoid double 

PWHT. In fact, MT is much more economical compared to RT. 

We saved a lot following above sequence with Alloy steel 

welding in a petro- chemical project. But choice is yours.

Dear Azam,

It is bettter to do after PWHT, so that after  stresses are relieved, surface cracks can be detected, if any....
