This kind of Non Destructive Testing can be carried out only on ferromagnetic components. A piece or a ferromagnetic component, if subjected to magnetization, highlights outcropping discontinuities on the surface, or placed immediately below it (few millimeters) which create a dispersion of the magnetic field. The particles of the magnetic detector are concentrated in this area indicating the presence of a discontinuity.
To run the Magnetoscopic Testing Rovergamma has:
- Magnetic Yokes
- Magiscop 3000 cca
