01MPI — magnetic particle inspection
Magnetic Particle inspection is used for the detection of surface and near-surface flaws in ferromagnetic materials and is primarily used for crack detection in materials which can be strongly magnetised. An electric hand-held yoke or fixed bench unit is used to produce a magnetic field in the part and fine iron particles suspended in a liquid are applied to the part using black ink with a white painted background or fluorescent ink and use of a UV lamp (requires a darkened area).
