Dear expert,

  Could you please give us your feedback & return experience about impact of PWHT (Heat treatment in general) in defect.

Could  size of porosity (volumic defects) can change after PWHT especially for ally steels ?

Any information for surfacic defects ?

Could you please confirm and give us some reference from codes and/or litterature.

Thank you very much.
