Magnetic Particle Testing is a relatively low cost, yet highly effective nondestructive testing method used to identify surface and near-surface defects in ferrous metal parts or components, including castings, forgings, weldments and machined or stamped parts.

MPI TESTING

This website was developed to answer basic questions about Magnetic Particle Inspection (MPI), also known as Magnetic Testing (MT) and Mag Particle Testing - from how MPI works and the steps used during the inspection process to the type of equipment and training required to become certified in magnetic testing (MT). Plus, you'll even find links to resources you can download in PDF format that will help you learn more about this exciting nondestructive testing method.

To help get you started, here are quick links to the information on this website:

MT METHOD - Learn how magnetic particle testing works.

MAGNETIC PARTICLE INSPECTION - Discover the steps involved in the wet mag particle inspection process.

MPI EQUIPMENT - The equipment is used for MPI.

STANDARDS - The international standards that establish the parameters and best practices for controlling the application of the magnetic particle testing method.

RESOURCES - Links to PDF publications you can download to learn more about MPI.

TRAINING & CERTIFICATION - Considering a career as an NDT tech? We detail the current requirements for Level I, II and III MT Certification through the American Society of Nondestructive Testing (ASNT).


NADCAP-accredited nondestructive testing

Magnetic particle inspection (MPI), also know as Magnaflux, is a highly-sensitive nondestructive test (NDT) that identifies defects on the surface and shallow subsurface of ferromagnetic materials such as iron, nickel, cobalt and some of their alloys.
