Magnetic Particle Testing Instrument

Magnetic flaw detectors utilize the principle that when ferromagnetic materials are magnetized, surface defects create leakage magnetic fields that attract magnetic particles, thereby revealing material flaws such as cracks. They are used for the surface inspection of metal components and are commonly employed in the quality testing of welded parts, castings, and forgings.
Selection
Select the magnetization method based on the magnetic properties of the material being inspected, determine the type of magnetic powder according to the required detection sensitivity, match the magnetization device with the shape and dimensions of the workpiece, choose portable or fixed equipment based on the inspection environment, and verify the flaw detection effectiveness in accordance with standard specifications.
