Magnetic Particle Inspection or Magnaflux as it is sometimes called uses magnetic leakage fields to detect surface and subsurface cracks and discontinuities. Magnetic particle testing is done by inducing a magnetic field in a ferromagnetic material and dusting the surface with iron particles (either dry or suspended in a liquid). Surface imperfections will distort the magnetic field and concentrate the iron particles near imperfections, thus indicating their presence. Magnetic particle testing can be brought to your facility or can be performed in our facility, depending upon your application and time frame.
