MAGNETIC PARTICLE INSPECTION (MT) SERVICE

Magnetic particle testing (MT) is a non-destructive testing method frequently used to detect surface and subsurface defects in ferromagnetic materials. Ferromagnetic is defined as a term used for materials that can be magnetized by a magnetic field or strongly attracted by a magnetic field. Magnetic particle testing (MT) is fast and relatively easy to perform, and surface preparation is not as critical as other NDT methods. The most important limitation is that the material being inspected must be made of a ferromagnetic material such as iron, nickel, cobalt, or one of their alloys.

This method is used to inspect various product forms including castings, forgings and welding. Structural steel, automotive, petrochemical, power generation and aerospace industries are a few examples that use magnetic particle inspection.
