Magnetic Particle Testing

Magnetic Particle Inspection is used to examine surface and near surface defects. Magnetic particle inspection uses magnetic field and small ferrous particles (iron filings) to detect flaws in test object. By inducing a magnetic field in a Ferro-magnetic material and then dusting the surface with iron fillings, any surface/near surface flaws will be visibly shown by a accumulation of iron filings.

Technique capability:

  • Only ferromagnetic materials can be inspected.
  • Detects Surface & Near Surface defects
