Description
 

This products use testing method by utilizing the Yoke method, to magnetize with some or all of test

flaws placed between magnet electrodes and detect flaw of the object to be tested by inducting

partial linear magnetic field to the test piece.

This method enables to easily and rapidly detect surface flaw of forged products or welding, part, etc 

Features

• To achieve the best inspection effciency

• To form a strong manetic field with a AC or DC type

• To apply dry, wet and fluorescent magnetic particles

• Excellent durability by using a molding type of rubber material with strong

  water-proof, shock  resistance 

• To test various objects to be tested by connecting middle poles

Principles of Magnetic Particle Testing

When the material or part under test is magnetized, discontinuities which lie in a direction generally

transverse to the direction of the magnetic field will cause a leakage field to be formed at and above 

the surface of the part. The presence of this leakage field and therfore the presence of the discontinuity

is detected by the use of finely divided ferromagnetic particles applied over the surface , some of these

particles being geared and held by the leakage field.

The magnetically held collection of particles forms an outline of the discontinuity and indicates

its location, size, shape and extent.
