MT magnetic particle inspection Symmetry Detection

MT magnetic particle inspection Magnetic particle inspection is to detect a ferromagnetic surface and near surface defects detection method used. When the magnetization of the workpiece, if the workpiece surface or near-surface defects, defects due to the reluctance of the magnetic flux leakage is generated is increased, the formation of the local magnetic field, the magnetic powder will show the shape and position of the defect in here, in order to determine the presence of defects. Magnetic particle inspection types: 1, according to the magnetization direction of the workpiece can be divided into circumferential magnetization method, longitudinal magnetization method, complex magnetization method and rotational magnetization method. 2, according to the use of the magnetizing current can be divided into: DC magnetization method, the half-wave DC magnetization method, and ac magnetization method. 3, according to a flaw detection using magnetic powder formulation can be divided into powder dry method and wet method.
