Magnetic Particle Inspection (MPI) is a non-destructive testing method that can detect surface and subsurface flaws in ferromagnetic materials.
Magnetic particle inspection is often carried out to help determine an item’s fitness for use or conformity. This quick and relatively easy to apply technique is widely used in all industry sectors including aerospace, automotive, petrochemical, structural steel and power generation to inspect a variety of products and equipment such as engine, suspension and braking system components, castings, forgings and weldments.
