Magnetic Particle Inspection (MPI) is a crucial NDT method for detecting surface and near-surface defects in ferromagnetic materials. Through advanced magnetic particle testing, professionals can identify cracks, seams, and other flaws that could compromise structural safety. Whether referred to as MPI inspection or MPI testing, this technique ensures reliable quality control in critical industries. By integrating NDT magnetic particle testing, engineers maintain structural integrity, prevent failures, and extend the service life of components, making it an essential part of industrial safety protocols.
