Magnetic Particle Testing ,also known as Magnetic Particle Inspection (MPI/MPT/MT) is a Non Destructive Testing Technique used for detecting surface as well as sub-surface defects. This video contains the practical demonstration of MPI by using two techniques which shall be shown in the video. For this method following equipment/item are necessary: 1. Yoke (An Electromagnet) is a device which can be used for Magnetic Particle Testing. Unlike Permanent Magent, we can control the strength of the Magnetic Field and the following Yoke provides a Longitudnal Magnetic Field. 2. Supramor 4 Black which consists of very finely divided black magnetic particles suspended in high flash point odourless kerosene designed to provide good particle mobility. The black particles have been selected for their high magnetic response, low coercivity (to avoid coagulation) and prolonged operational life. 3. Field Indicator such as Pie gauge which consists of 8 ferromagnetic pieces attached using Non Ferromagnetic Material. 4. Color Contrast using WCP 712 which is is a suspension of a white pigment in a resin base, which utilises a fast drying, flammable solvent system. It is used in conjunction with Supramor® 4 Black and provides an excellent contrasting white background when dark steels are being used. The following video has been edited in such a way that the procedure of Non Destructive Testing can be understood or learnt . The following was done at BITS Pilani Dubai and we shall also be putting up lecture classes for the following.
