Description

Technical Field

[0002] Magnetic particle inspection utilizes the interaction between the leakage magnetic field at the defects of the workpiece and the magnetic powder. It utilizes the difference in magnetic permeability between the surface and near-surface defects of steel products (such as cracks, slag inclusions, hairline, etc.) and the magnetic permeability of steel. After magnetization, the magnetic field at the discontinuity of these materials will be distorted, forming a leakage magnetic field on the surface of the workpiece where some magnetic flux leaks, thereby attracting magnetic powder to form magnetic powder accumulation at the defects - magnetic traces. Under appropriate lighting conditions, the defect position and shape are revealed. By observing and interpreting the accumulation of these magnetic powders, magnetic particle inspection is achieved.

[0003] During the magnetic particle inspection process, the workpiece needs to be sprayed with magnetic suspension liquid first, and then the workpiece is placed between the magnetic plates to allow the magnetic suspension liquid to accumulate at the damaged part of the workpiece.
