Magnetic flaw detection
Introduction
Magnetic Particle Inspection (MPI) is a nondestructive testing technique used to detect surface and near-surface discontinuities in ferrous materials. The technique is mostly carried out using a portable yoke or a permanent magnet, to create a magnetic field in the part under test. P......
