Description

technical field [0001] The invention relates to the technical field of steel material detection, in particular to a magnetic particle detection device and a detection method for all-round detection of steel structures. Background technique [0002] Magnetic particle testing is a fast and non-destructive testing method used to detect fatigue cracks and other surface defects in steel materials. During the test, the test piece is magnetized. After the steel material workpiece is magnetized, due to the existence of discontinuity, the surface of the workpiece and The magnetic field lines near the surface are locally distorted to generate a leakage magnetic field, which absorbs the magnetic powder applied on the surface of the workpiece, and forms visually visible magnetic marks under suitable light, thereby showing the position, size, shape and severity of the discontinuity, and It is called magnetic particle inspection or magnetic particle inspection, and it is one of the five c...
