Magnetic flaw detectors
Magnetic particles Testing (MT) allows for quick and reliable detection of any surface defects in ferromagnetic materials, caused by cracks, heterogeneous structure, foreign insertations, material discontinuities. This method is applied when detecting flaws at (the so-called "open flaws") or near ("closed flaws") the surface of the test piece. Therefore, it may be used at elements with thin galvanic coatings.
