Penetrant

Dye Penetrant System 

DIFFU-THERM ® penetrant testing

Penetrant is used to display errors, such as Cracks, overlaps, wrinkles, pores and fusion, which are open to the surface. It is mainly used in metal workpieces, but can also be used for other materials, provided that such materials are not affected by the test equipment and / or non-porous.

Just ask the surface cracks in highly stressed workpieces are the most dangerous mistakes, because they can result due to the notch effect to an early break. 

For the identification of such surface cracks is recom mended especially destructive testing after DIFFU-THERM ® penetrant testing .

Magnetic-Particle Testing System

DIFFU-THERM ® – Magnetic particle inspection

In general magnetic particle inspection by DIFFU-THERM ® is also an extremely sensitive method of non-destructive testing, but its use is restricted to ferro-magnetic materials.

The magnetic flux leakage method used to demonstrate microscopic defects on the surface and in the interior of ferromagnetic workpieces.
