Magnetic Particle Testing (MT)
Available from RNDT Inc.
Magnetic particle testing is done by inducing a magnetic field in a ferro-magnetic material and dusting the surface with iron particles (either dry or suspended in a liquid). Surface imperfections will allow the magnetic field to leak out of the part, distort the magnetic field and concentrate the iron particles near imperfections, thus indicating their presence.
Magnetic Particle Testing, or Magnaflux as it is sometimes called, uses magnetic leakage fields to detect surface and subsurface cracks and discontinuities.
Our Magnaflux 6000 amp bench units with 8' head stocks, portable power packs, yokes, prods, black lights and all required accessories provide the foundation for RNDT to provide quality MT visible and fluorescent, wet and dry examinations in both the lab and field.
