Nondestructive Testing (NDT) is the name given to the processes designed to verify the integrity of a structure in such a way that the performance of that component is not impaired by the test.

This article will list and explain why each magnetic particle inspection accessory is needed to validate the system performance of an inspection.

The conventional measurement of mechanical hardness, for instance, in steel, is usually carried out using the same principle. A mechanical indenter is forced towards the surface of the workpiece, penetrating it and leaving an imprint. 

Magnaflux is introducing a new multi-direction magnetic particle wet bench – one that is specifically designed for speed. The Universal WE wet bench is designed with automotive customers in mind. 

It is true that magnetic particle testing (MT) is one of the oldest NDT methods, and over the years has proven itself to be not only reliable, but cost effective, when it is applied properly with qualified personnel. 

Each day, facilities across the globe turn to nondestructive testing (NDT) to verify the reliability of parts or materials without causing damage. One of the most popular of these methods is magnetic particle inspection (MPI)—a form of NDT that uses magnetism to detect surface and near-surface defects, cracks, seams or stress points in ferromagnetic materials before parts and materials are placed into service.

On April 20, three days after a Southwest Airlines Boeing 737-700 experienced an engine failure due to a fractured fan blade, resulting in the death of a passenger, the U.S. Federal Aviation Administration issued an emergency airworthiness directive that requires operators of CFM56-7B engines with more than 30,000 flight cycles to perform a one-time ultrasonic inspection of all 24 fan blades to detect cracking.

Magnetic particle inspection is widely used to inspect production parts, parts in service and for periodic inspection of structures such as bridges, aircraft engines and landing gear.

A variety of recognized methods can be used to determine the thickness of organic coatings.

Magnetic Particle Testing (MT), one of the oldest and most reliable NDT methods, is often not given the recognition it deserves.
