Magnetic particle crack detection is a non-destructive testing method which is used for surface and sub-surface defects of ferromagnetic materials. TMM designs and manufactures part specific test systems in addition to stationary benches and mobile units.

Eddy current test method is based on electromagnetism, which is basically the study of conducting materials. Eddy currents induced within conductors by electromagnetic induction.

Acoustic resonance testing is a new non-destructive testing method that allows rapid and inexpensive 100% testing of a wide range of work-pieces.A test piece, after suitable excitation, oscillates at certain characteristic modes and frequencies.

Ultrasonic testing is based on the propagation of ultrasonic waves in the material tested. The probe sends high frequency ultrasonic waves into the material and these waves reflected back from the flaw surface.

After an external magnetic field is removed, residual magnetism is left behind in ferromagnetic materials. Residual magnetism may cause problems in following process or usage of the component.

Special testing accesories are needed to adjust and check testing parameter of non-desctructive processes. According to testing method different type of accessories and consumables are available.
