Magnetic particle Inspection (MPI) is a nondestructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as ironnickelcobalt, and some of their alloys.

The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak, since air cannot support as much magnetic field per unit volume as metals.

To identify a leak, ferrous particles, either dry or in a wet suspension, are applied to a part. These are attracted to an area of flux leakage and form what is known as an indication, which is evaluated to determine its nature, cause, and course of action, if any.

Visual inspection (VT) is a popular weld quality inspection method and is one of the most common Non-Destructive Testing (NDT) methods. It involves a visual testing of welds and is capable of detecting surface-breaking defects, as many welding flaws are on the surface and can easily be detected via this weld inspection procedure.

Visual inspection is a vital part of an in-service inspection, which may or may not be backed up by other NDT methods. The examinations made are for fatigue cracks creep failure, corrosion, erosion, abrasion, mechanical damage, wear and tear, distortion, and poor workmanship.
