What's The Magnetic Testing ?

- Jun 02, 2020-

Magnetic particle flaw detection is a non-destructive testing method for detecting defects on or near the surface of ferromagnetic materials through the accumulation of magnetic particles in the leakage magnetic field near the defect. The work piece made of magnetic materials such as iron and steel is magnetized, and the magnetic flux of the defective part is used to absorb the characteristics of the magnetic powder, and the flaw detection method of displaying the surface defects and near surface defects of the detected object according to the distribution of the magnetic powder. The flaw detection method is characterized by simplicity and intuitive display.
