NATTS MAGNETIC PARTICLE TESTING SERVICES

Magnetic particle testing or MPT is a nondestructive testing methodology for locating surface and close to surface discontinuities in ferromagnetic materials.

MPI or Magnetic Particle Inspection distinguishes surface and close surface defects, for example, breaks, creases and laps in ferromagnetic materials, and is utilized to evaluate area, size, shape and degree of those flaws.

ESSENTIAL PROCEDURE OF MPT

  • Component pre-cleaning
  • Introduction of magnetic field
  • Application of magnetic media
  • Exposition of magnetic particle indications

WORKING OF MAGNETIC PARTICLE INSPECTION

A ferromagnetic test specimen is magnetized with a strong magnetic field created by a magnet or special equipment.

If the specimen contains a discontinuity, the discontinuity will interrupt the magnetic field flowing through the specimen and a leakage field will occur.

A ferromagnetic test example is charged with a solid attractive field made by a magnet or unique hardware.

On the off chance that the example contains an irregularity, the brokenness will interfere with the attractive field coursing through the example and a spillage field will happen.

It depends for its operation on proven fact that once the material or part underneath test is magnetized, discontinuities that exist a cause leakage field to the direction of the magnetic field will cause a leakage field to be formed at and on prime of the surface of the part.

Finely processed iron particles coated with a dye pigment area unit applied to the check specimen.

These particles area unit drawn to leak fields and can cluster to create a sign directly over the discontinuity. These indications are visually detected underneath correct lighting conditions.

Magnetic particle inspection can distinguish both production discontinuities (seams, laps, grinding cracks and quenching cracks) and in-service damage (fatigue and overload cracks).
