Permanent Magnet Yoke Flaw Detector

Permanent magnet yoke flaw detectors generate a magnetic field through permanent magnets to magnetize the surface of ferromagnetic materials. When defects are present in the material, magnetic flux lines leak to form a leakage magnetic field, which attracts magnetic powder to reveal traces. It is used to detect surface cracks in welded components, castings, and forgings. The device requires no power supply during operation, making it suitable for field work.
Selection
When selecting, consider the thickness and shape of the material to be tested. Thicker workpieces require higher lifting force. Choose the magnetic pole spacing based on sensitivity requirements, with a spacing of 100-150 mm for conventional defects. Environmental conditions determine the type of magnetic yoke; use a waterproof type in humid areas. The type of magnetic powder is determined by the surface condition; fluorescent magnetic powder is used for rough surfaces.
