Magnetic particle inspection (MPI) also known as magnetic particle testing (MPT) is a non destructive test (NDT) method used to check for surface and near-surface discontinuities in ferrous materials. Our magnetic particle testing is performed on-site or in one of our state-of-the-art laboratories. 

Because this method relies on a magnetic field to produce results, it works best on ferrous materials, like nickel, iron, cobalt, and some alloys. Components like billets, bars, castings, forgings, fasteners, weldments and extrusions are also commonly tested using magnetic particle inspection.

Magnetic particle inspection methods

Trust the NDT Experts at ºÃÉ«TV

Magnetic particle inspection can be performed using a wet or dry method, depending on the application. In both methods, the product is electrically charged to create a magnetic field. Then, ferrous iron particles are applied to the part in a dry or wet suspension. 

If there is a crack or other defect present, the particles will be attracted to the flaw and build up around the leakage to for an “indication.” The indication is then evaluated to determine the characteristics and cause of the defect. Results allow our Engaged Experts to understand the type and severity of any discontinuities on the part’s surface or sub-surface. 

Why choose ºÃÉ«TV for MPI testing?

By examining the nature, location and extent of an indication, our highly trained and experienced inspectors can determine the origin and cause of both surface and near-surface discontinuities. 

ºÃÉ«TV operates full-service non-destructive testing (NDT) and magnetic particle inspection laboratories that utilize advanced equipment capable of performing quality inspections for virtually any form of ferrous material, component or assembly.
