This method involves the component under inspection being magnetized, this magnetization process is supplemented by the application of ferromagnetic particles to the already magnetized surface. The magnetic particles are attracted to areas of flux leakage (escaping magnetism) and indications formed at that point. This method is used to test welds, castings, and forging for surface or slightly subsurface defects. However MT can only be used to inspect materials that can be magnetized, i.e. ferromagnetic materials.
We can provide Magnetic Particle training courses and examinations suitable for any of the following certification schemes at Level 1 & 2 SNT-TC-1A/ CP 189 in accordance with your company written practice.
If a candidate wishes to go direct to Level 2 without first taking the Level 1 route, the minimum requirements are the total accumulative requirements of both Level 1 and 2.
We can also provide Preparation training for ASNT Level 3.
Note: NDT Academy can tailor the syllabus to satisfy the requirements of an individual’s company specific written practice if requested.
