Re: [MW:18053] RE: 18041] metallurgy of weld joint PWHT

Dear Ramon Kondori Sir.


Earlier I was believing the same what you wrote in the reply.

Regarding the 3rd point u mentioned needs more clarification.,because no microstructure changes during pwht as pwht temperature is below the lower critical temperature of the metal but brittleness/hardness changes.

Please clarify your 3rd point
