Magnetic Particle Testing (MPT)

MPI is a nondestructive testing (NDT) technique used to identify surface and subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and certain of their alloys. We provide magnetic particle inspection services on-site utilizing yoke and coil magnetizing equipment, as well as dry powder, wet magnetic particles, and wet fluorescent magnetic particle techniques. Magnetic Particle Inspection (MPI) is a cost-effective and speedier non-destructive testing technology commonly utilized in the aerospace, locomotive, automobile, power generation, nuclear, and petrochemical sectors.

Crank shafts, cam shafts, connecting rods, engine gears, landing gear, bearing caps, engine blocks, motor shafts, engine bolts, nuts, washers, threaded bars, studs, pipe joints (fabricated joints, welds), etc. are the most typical examples.

APPLICATIONS

• Most weld discontinuities open to or near the surface
• Most suitable for cracks, laps, seams, voids, pits, subsurface holes, and other surface or slightly subsurface, discontinuities in ferromagnetic materials

ADVANTAGES

• Relatively economical and expedient
• Test equipment is considered portable
• Unlike liquid penetrant, magnetic particle can detect some near surface discontinuities
• Can inspect through thin coatings
