Background

The continuity of the magnetic line of force in nature can be always maintained. When a ferromagnetic workpiece is placed in a magnetic field that saturates the workpiece, magnetic field lines are directed through the workpiece. If the magnetic field lines encounter discontinuities (i.e., cracks, inclusions, porosity, etc.) in the workpiece material, the magnetic field lines bypass these lower permeability (higher reluctance) regions and leak out of the workpiece surface to form a "leakage field". Thus, magnetic poles are generated on two sides of the defect, and magnetic powder (or magnetic suspension) is adsorbed around the defect such as a crack.

Clamping mechanism among the magnetic particle flaw detector plays the effect that supports the work piece and switch on the magnetizing current, and current magnetic particle flaw detector clamping mechanism adopts the electrode to compress tightly fixed work piece each other and switch on the magnetizing current mostly, nevertheless to coupling class dysmorphism work piece, adopts this kind of centre gripping mode and work piece can not carry out better laminating, and the installation is inconvenient, and the electrical contact performance is bad, and this technical problem of this field personnel urgent need to be solved.
