Is a non-destructive testing method used for surface breaking (slight sub-surface) defects. MPI is fast and relatively easy to apply, and part surface preparation is not as critical as it is for other NDT methods. These characteristics make MPI one of the most widely utilized non-destructive testing methods, especially suited to in service inspections for the purpose of locating and identifying fatigue related failures. It is also widely used in the manufacturing / welding industry to locate process faults in weldments, both prior to completing the welding as well as after completion of welding processes and thermal cycles
