mpi crack testing

Dec 02, 2020 · Toward the end of this decade, our industry will realize a full century since the inception of the magnetic particle inspection method. Since that discovery by Alfred Victor de Forest in 1928, this methodology has been the inspection of choice for production and in-service surface and near-surface discontinuity detection for nearly every form of ferromagnetic component.

The smaller the defect, the longer the penetrating time. Fine crack-like apertures require a longer penetrating time than defects such as pores. When the part to be inspected is made of a material susceptible to magnetism, it should be inspected by a magnetic particle inspection method if the equipment is available.
