AC/DC Magnetic Particle Flaw Detector

The AC/DC magnetic particle flaw detector magnetizes workpieces through an electromagnetic field, causing leakage magnetic fields to form at surface defects, which attract magnetic particles to reveal traces. It is used for detecting surface cracks in ferromagnetic materials and inspecting defects in welded components, castings, and forgings during mechanical manufacturing and equipment maintenance.
Selection
Select DC (deep defects) or AC (surface defects) based on the thickness of the material being tested; choose contact-type or coil magnetization methods according to the shape of the workpiece; consider portability needs by selecting weight and size; review magnetic particle compatibility and sensitivity verification reports; check power supply configuration and safety certifications.
