Permanent Magnet Flaw Detector

The permanent magnet flaw detector generates a magnetic field through permanent magnets to magnetize ferromagnetic materials. Surface or near-surface defects create leakage magnetic fields, which reveal traces by attracting magnetic powder. It is used to detect defects such as cracks and pores in steel structures and is suitable for on-site inspections of pipelines and welded components.
Selection
When selecting, consider the magnetic permeability of the material being tested and the depth of defect location. Match the pole spacing according to the shape and dimensions of the workpiece. Use fluorescent magnetic particles in humid environments. Check the instrument's residual magnetism index and adjustable magnetization range, and opt for a lightweight design for easy portability and operation.
