Magnetic particle testing (MT) is a widely applied non-destructive inspection method. It is used for detecting surface and subsurface irregularities in ferrous parts. With our broad range of approved and highly efficient technologies and equipment we can support you in many ways.

Magnetic particle testing is a non-destructive testing method in order to detect surface and sub-surface irregularities in ferrous parts. As a first step a magnetic field is put into the part tested. The magnetization can be direct (electrical current is passed through the test object) or indirect (magnetic field is applied from an outside source). Ferrous iron particles (dry / wet suspension) are then applied to the part. In case of an area of flux leakage, the particles are attracted to this area and form an ‘indication’. The inspection can be performed under UV(A)
