Basic Principle – Magnetic Particle Testing (MT)

Magnetic particle testing is accomplished by inducing a magnetic field in a ferromagnetic material and then applying the surface with iron particles. The surface will produce magnetic poles and distort the magnetic field in such a way that the iron particles are attracted and concentrated making defects on the surface of the material visible.


This course provides detailed theoretical and practical information on all the commonly encountered Magnetic Particle Testing (MT) techniques. Candidates will have the opportunity to use the various techniques on welds, castings and wrought products.
This course meets, the training hour requirements as specified by the American Society of Non-Destructive Testing (ASNT) Recommended Practice documents SNT-TC-1A.
