From its inception, Klaus Gross GmbH & Co. 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 inspection 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.
Ultrasonic testing is another volume process and a non-destructive test. Ultrasonic testing is used to detect lack of homogeneity and defects of all types. This applies to the complete cross-section and the surfaces of test objects made of materials capable of conducting sound.
The process is based on the interaction between an ultrasonic impulse emitted into the test object and its reflection, shadowing, refraction or attenuation when meeting boundary surfaces, discontinuities or the surface of a different material.
This influence can be measured in pulse-echo testing systems, radiographic techniques or resonance techniques and is used to detect discontinuities and defects in position, shape and size. Acoustic logging allows the determination of wall thicknesses and material characteristics.
