What Is Magnetic Particle Inspection?
Magnetic Particle Inspection (MPI) is a precise non-destructive testing technique used to detect surface and near-surface discontinuities in ferromagnetic materials. The process involves magnetising a component and applying fine magnetic particles, which gather at any areas of flux leakage caused by cracks, seams, or other defects.
This visual indication allows skilled technicians to identify flaws that may not be visible to the naked eye but could significantly impact structural integrity. MPI is commonly applied to welds, castings, and critical components used across industries such as oil and gas, power generation, and heavy manufacturing — ensuring safety, reliability, and compliance.
