MAGNETIC TESTING (MT)

Magnetic Particle Inspection is a nondestructive testing method used for detecting surface and near 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.

This course requires no prior training or experience by the student in this method of NDT. The material is presented in a manner that promotes understanding and the ability to make immediate application. This is an excellent course for NDT trainees who must have Level I and II training in order to qualify for certification as well as facility personnel who are responsible for or oversee the application of testing or Quality Control/Quality Assurance.
