Magnetic particle inspection

磁粉探伤 Test Item Magnetic particle inspection
Purpose Detection of mechanical parts weld defects, such as measuring thickness
Test Range Ferromagnetic material products
   Brief introduction of magnetic particle inspection
       1. Definition: the detection method of the interaction between magnetic magnetic particle and magnetic particle using the magnetic flux leakage at the defect. (surface flaw detection)
       2, applicable scope: iron powder material; surface or near surface.
       3, display materials: magnetic powder。
       4, defect detection: magnetic mark.
       5, advantages: intuitive, fast, high sensitivity, amplification defects。
       6, shortcomings: mild pollution, can not detect depth.
       7, the limitations of internal defects are not detected, the ferromagnetic material cannot determine the defect depth, and vertical lines to defect.
   Principle of magnetic particle inspection
       The magnetic field of the ferromagnetic material is magnetized in the magnetic field, and the magnetic flux passing through the workpiece. If there is a defect, it will cause a certain part of the magnetic field to leak out from the defect. Leakage magnetic flux is capable of adsorbing particulate magnetic materials. Thus forming an indication of the corresponding to the discontinuity.
