PWHT ( coil or Band width ) requirement

[nktqc]

What are the deciding factor for PWHT ( coil or Band width ) requirement.


Some specs/ codes say 75 mm , some say 50 mm , some say 150 mm. So what are the basic criteria for selecting the Width of Induction Coil?

The contractually specified requirements. If none are specified, then you can follow ISO 17663 or AWS D10.10 as appropriate and as seen fit.
