Magnetic Particle inspection is used to identify surface and near surface discontinuities in ferromagnetic materials such as steel and iron. The technique uses the principle that magnetic lines of force (flux) will be distorted by the presence of a discontinuity. Discontinuities (for example, cracks) are located from the flux distortion following the application of fine magnetic particles to the area under test.
Typical Applications:
Inspection of casting, forgings and welds.
Non-destructive testing (NDT) -Magnetic particle testing available on and off site.
