Magnetic Particle Inspection (MPI) Equipment
Magnetic Particle Inspection or Magnetic Particle Testing (MPI/MPT/MT) is a non-destructive testing method for detecting surface and near-surface discontinuities in ferromagnetic materials. A magnetic field created with AC or DC is applied through the material, distorting the magnetic flow at a surface or near-surface flaw in iron, cast iron, and ferromagnetic steel.
With PROMAG’s magnetic particle inspection (MPI) equipment, customized automated magnetic particle inspection (MPI) system, and AI defect inspection & recognition robot, the NDT’s magnetic particle inspection process can be performed reliably and efficiently.
During the manufacturing or repair activities, Magnetic Particle Testing / MT is required directly by standards or the customer. Basic methodical standards both are ASTM E1444 and EN ISO 9934 - 1, 2, and 3.
