[MW:25227] Re: PWHT

Dear Ishwar,

You have simulated the welding & parent material with 2 cycle of PWHT.
This may effect your mechanical properites (specially impact & hardness), kindly take the test piece & simulate what you have carried out on the job.

The job can be accepted, If the test result meets the code requirement.


Regards
MK

Dear experts

My query is what happens if the soaking time during PWHT is increased beyond the specified minimum time. I know section 8 days minimum soaking time only.
