Hi,

Could someone throw some light on the the following topics:

1. Which method (Yoke or Prod) should be used to inspect Fillet welds with Magnetic Particle Inspection.

You only can use the prod method when putting the electrodes on the weld surface because of the magnetic field lines, in my opinion a Yoke will be the best method. Beside that when you don’t have proper contact with the probes there is a risk of arcs which can cause copper penetration in the surface of your material.

You can use Prods with Dry Method. You can try with 8A Red MPI powder of
Magnaflux make.
