[MW:1071] Re: PWHT by Induction Heating Method

as far as i know it is true to some extent induction heating is used
for bending in the preffabrication shops, but i am not aware of any
for PWHT of welds at site by induction heating.

In particular how it will effect in higher thickness (>30mm) over
conventional method, what is the advantage?
