Magnetic Particle Testing, MPT, is a relatively simple test method that can be applied to finished articles, hot rolled bars, castings and forgings. It can also be used to check that the processing operations, such as heat treating and machining and grinding, did not uncover or cause discontinuities.
Because magnetization of certain metals is possible, small particles that are attracted to magnetic fields are applied to the surface of the test object after or during induction of a magnetic field, thereby detecting certain discontinuities (variations in material composition) economically. While one of the most used nondestructive testing methods, magnetic particle testing is limited to disclosing surface or near to the surface indications.
NDT Inspectors maintain Level II certifications in accordance with SNTTC-1A standard.
