Magnetic Particle Testing – MT

It is a non-destructive test method for detecting surface and subsurface discontinuities in ferromagnetic materials. The test method involves the application of a magnetic field externally, or the use of an electric current directly through the material that creates the magnetic field in the material. At the same time, ferromagnetic particles applied to the test surface are visible.

The presence of surface discontinuities or discontinuities just below the surface causes deformation of the magnetic field, which in turn causes magnetic leaks in the flaws. Magnetic particles are attracted by the magnetic leakage in the discontinuity zone and adherent to the edges where its shape is drawn. This test is a very sensitive test method. This method is not used for non-ferrous materials and austenitic stainless steel. There are several ways of magnetizing tested parts.

Instrumentation equipment

Magnetisation methods:

Our Instrumentation:

ALL TESTS ARE ACCREDITED AND PERFORMED BY THE PERSONNEL WITH QUALIFICATION ACCORDING TO STN EN 9712 LEVEL II AND III.

When controlling larger numbers of the same products, we prepare our own test equipment to ensure the required magnetic field size that will be able to identify flaws in the required range for a particular product.
