Results for tag: "Magnetic Particle Inspection"

Magnetic Particle Inspection (MPI) is a non-destructive testing (NDT) method used to detect surface and subsurface flaws in ferromagnetic materials. It is used in engineering to detect cracks, laps, seams, inclusions, and other discontinuities in the material. MPI is a relatively simple and cost-effective method of testing, and is often used in the aerospace, automotive, and power generation industries. The process involves the application of a magnetic field to the material, followed by the application of a magnetic particle suspension. The particles are attracted to the areas of the material where the magnetic field is disrupted, indicating the presence of a flaw. The particles are then made visible using a UV light or other method. MPI is often used in combination with other NDT methods, such as ultrasonic testing, to provide a more comprehensive assessment of the material. Companies in the MPI market include Magnaflux, Olympus, Zetec, Eddyfi, and GE Inspection Technologies. Show Less Read more
