MPI Inspection Testing

Magnetic Particle Inspection (MPI)

MPI – Magnetic Particle InspectionApplied Inspection offers a cost effective MPI service to a wide range of industries at highly competitive rates.

We are able to undertake MPI up to 3000 amps in our laboratories or on site – 24 hours a day, seven days a week. With over 90 full time staff, we are equipped to provide a rapid response and a fast turn around as well as a collection and delivery service.

Magnetic Particle Inspection is used on welds, castings and forged ferro-magnetic materials in order to detect cracks and flaws on the surface or very near to the surface.

There are several types of electrical currents used in MPI. For a proper current to be selected one needs to consider the part geometry, material, the type of discontinuity you’re looking for and how far the magnetic field needs to penetrate into the part.
