This weld looks perfectly fine... until Magnetic Particle Inspection (MPI) reveals what the naked eye cannot see.
MPI uses magnetic fields and fine particles to detect surface and near-surface discontinuities that may compromise weld integrity, safety, and long-term asset reliability.
From pipe welds and girth welds to heat-affected zones (HAZ), MPI remains one of the most trusted NDT methods for identifying critical defects before they become costly failures.
Because in inspection, the most important defects are often the ones you can't see.
