Non-destructive testing:

From its inception, Klaus Gross KG has been in the business of non-destructive material testing, which allows us to look back over a treasure-trove of 30 years of experience. This experience, combined with a high degree of flexibility and highly motivated staff, has characterised us from the beginning.

We can carry out any process we offer either at our premises or at the client's location. This applies to HT, PT, MT, RT, UT or VT tests; on request, we can provide a complete evaluation and documentation directly on the spot. We can ensure this as we use only personnel qualified at Level 2 in our operation. For test supervision, there is also a Level 3 tester in house.

For many years, our range of activities has included the acceptance of drilling rods. In this respect, we have trained some of our employees in the NS2™ standard, which ensures the highest level of quality.
See the sub-menu points for a quick overview of the testing processes we carry out. Our skilled personnel are available for questions at any time.

 

RTRadiographic testing


Radiographic testing is one of the non-destructive tests that is a volume process, like ultrasound testing.

Radiographic testing (X-ray testing) is one of the most-used processes in non-destructive testing (NDT), along with ultrasound testing, and is used for inspecting weld seams and cast and forged parts for various applications.
Radiographic testing (RT) requires high-energy radiation, such as X-ray and gamma radiation, that is able to penetrate material.

Lack of homogeneity and flaws in the complete cross-section of the workpieces in materials of all types lead to differences in attenuation of the penetrating radiation. The differences in attenuation can be documented as different shades of grey by using a film lying behind the test object and special image converters.

In the projection image of the component, variations in material thickness, volume defects and cracks can be recognized with a suitable radiation angle as differences in grey level. Contrast and defect resolution are functionally dependant on the component thickness, the quality of the radiation source, the radiation scatter and the type of film.
