I did think that it was a question from a parallel universe where inspection is performed with heating bands.

A PWHT is a kind of a vaccine given to a metal throught the heat.That way we rearrange the molecules of the material so that they can support some kind of metalic illness.

NDE shall be done before or after PWHT to verify the soundness of metal or weldments. PWHT is not testing techniques. To relieve Residual stresses and to get original properties
