Magnetic particle testing

Magnetic particle testing


At TGI we perform magnetic particle inspection to check welds regarding to NDT.

The method can be used to find cracks and inclusions in or immediately below the surface.

Magnetic particle inspection is performed by magnetizing the subject to be examined, after which the surface is applied to an iron powder.

Faults and cracks will interfere with the magnetic field on the powder will hold over a possible crack.

With this method it is possible to distinguish between harmless and dangerous cracking.

TGI has chosen method and fluid that does not harm the environment or material.

Rapidly, efficiently and without danger of destroying the material or the environment, it is possible to obtain a deeper insight into

the construction's assembly with magnetic powder testing.
