Magnetic Particle Inspection is a nondestructive testing method used for detecting surface and sub- surface flaws and defects. MPI is fast and relatively easy to apply, and surface preparation is not as critical as it is for other NDT methods. These characteristics make MPI one of the most widely utilized nondestructive testing methods. MPI uses magnetic fields and small magnetic particles similar to iron filings to detect flaws in components. The only real limitation is that the component being inspected must be made of a ferromagnetic material such as iron, nickel, cobalt, or one of their alloys. The method is used to inspect a variety of product forms including castings, forgings, and weldments. The structural steel, automotive, petrochemical, power generation, and aerospace industries are a few examples that utilize magnetic particle inspection. Underwater inspection is another area where magnetic particle inspection may be used to test items such as offshore structures and underwater pipelines.

- Effects of Discontinuities on Materials
- Principles of Demagnetization
Upon completion of this course the participants would have complete understanding of the maintenance problems in process industry that can be easily identified by Magnetic Particle Inspection. They would be able to apply this technique on any critical plant asset. Participants would also be able to distinguish MPI over other NDT testing techniques keeping in mind economic factor as well.
This course is designed for Mechanical, Chemical and Industrial engineers working in plant condition monitoring divisions. It is equally beneficial for maintenance technicians directly implementing MPI to detect flaws in machine components.
