Re: [MW:22651] Grinding of weld joints after PWHT

I think no. My belief is reinforced by sometimes we replace the pwht with temperbead in which we grind the half bead. Expect views from other experts. 

 

 

Thanks & Regards

Dear,

Grinding afte PWHT may create or hardning the weld joint.  So it is better to do before PWHT.
waiting for the team input.
