ISO 9001:2015 & VCA* certified

Perfect for detecting defects in magnetic material

Magnetic Testing offers quick determination of defects caused after welding magnetic material, thus avoiding high repair costs later on. NDO Nederland also always includes an advisory report is, allowing you to avoid similar future problems.

Magnetic Testing or Magnetic Particle Inspection (MPI) is relatively inexpensive, while you get quick results. We often conduct our tests on site as well.

Advantages of Magnetic Testing

The main advantage of Magnetic Testing is it’s quick results as well as that it’s a relatively inexpensive. In addition, it is a typical form of Non-Destructive Testing, as it leaves practically no traces.

Depending on your wishes we use alternating current or direct current. Alternating current detects defects at the surface, while direct current can be used to detect defects up to 6 millimetres deep. The ultimately covered depth depends on the material we are testing.

Another advantage is that Magnetic Testing can be used for many different materials, provided they are magnetisable. This basically means all materials made of carbon steel, provided the coating is removed. In some cases a very thin layer of paint may remain on the surface.

Want a quick check to determine whether a joint welded in magnetisable material has any defects? Then Magnetic Testing the solution. It offers quick results and proves to be an easy way to exclude surface defects.

How does Magnetic Testing work?

Magnetic Testing is applicable on all magnetic materials at various moments. For instance after welding during construction, at grinding spots in the new development phase, but also during welding repairs. Thus you are ensured that the welding work does not have surface defects and also meets all requirements. Magnetic Testing can also be conducted at surface damages of parts or after maching such as turning and milling. Often Magnetic Testing is applied when a welding joint may have been over-stressed.
