This method involves the component under inspection being magnetized; this magnetization process is supplemented by the application of ferromagnetic particles to the already magnetized surface. The magnetic particles are attracted to areas of flux leakage (escaping magnetism) and indications formed at that point. This method is used to test welds, castings, and forgings for surface or slightly subsurface defects.
However MT can only be used to inspect materials that can be magnetized, i.e. ferromagnetic materials.
We can provide Magnetic Particle Inspection courses and examinations suitable for any of the following certification scheme PCN/SNT-TC-1A/NAS 410 – EN 4179.
We can also provide training for PCN/SNT-TC-1A/NAS 410 – EN 4179 NDT Level 3.
For PCN: Refer PCN General Requirements Document
For NAS410/EN4179/SNT-TC-1A: According to Written Practice.
For ACCP: Refer ACCP General Requirements Document
Will vary depends on the type of certification chosen
