Magnetic particle testing is the most sensitive method with respect to surface cracks and can be used in complex geometry of materials and on unfinished surfaces. MT is used for magnetic (ferromagnetic) materials e.g. steel and iron. The individual magnetization methods and the principles behind magnetization and demagnetization will be dealt with in this training course. Particular importance will be attached to process monitoring and checks on inspection equipment. Evaluation techniques typically used in the various industrial sectors will be presented along with the bodies of standards currently applicable.
