Magnetic Particle Testing Unit By Kyungdo Enterprise Co., Ltd.

Our firm is leading name in exporting, distributing, trading and manufacturing of Magnetic Particle Testing Unit to our patrons in Seoul, Seoul, Korea South. This products use testing method by utilizing the Yoke method, to magnetize with some or all of test flaws placed between magnet electrodes and detect flaw of the object to be tested by inducting partial linear magnetic field to the test piece. This method enables to easily and rapidly detect surface flaw of forged products or welding, part, etc.

Principles of Magnetic Particle Testing

When the material or part under test is magnetized, discontinuities which lie in a direction generally transverse to the direction of the magnetic field will cause a leakage field to be formed at and above the surface of the part. The presence of this leakage field and therefore the presence of the discontinuity is detected by the use of finely divided ferromagnetic particles applied over the surface , some of these particles being geared and held by the leakage field.The magnetically held collection of particles forms an outline of the discontinuity and indicates its location, size, shape and extent.
