Magnetic Particle Inspection

Dry Magnetic Particle Inspection

  • The part is magnetized.
  • Finely milled iron particles coated with a dye pigment are then applied to the specimen.
  • These particles are attracted to magnetic flux leakage fields and will cluster to form an indication directly over the discontinuity. 
  • This indication can be visually detected under proper lighting conditions

Wet Magnetic Particle Inspection

  • The part is magnetized
  • Fine iron particles coated with a fluorescent dye are suspended in a liquid which is flowed over the magnetized part.
  • These particles are attracted to magnetic flux leakage fields and will cluster to form an indication directly over the discontinuity.
  • A blacklight is required to illuminate the indication.
