Eddy current testing is a non-destructive method for inspecting metallic surfaces for defects such as cracks or imperfections. High-frequency electromagnetic interactions can be used to manually or automatically surface defects can be detected and evaluated manually or automatically, depending on the requirements.

Optical test method

Can be used on almost all surfaces

For the detection of defects e.g. cracks or pores

‍

Optical test method

Can be used with all magnetizable materials

For the detection of cracks and near-surface flaws

Ultrasonic testing is a non-destructive testing method used to inspect components made of sound-conducting materials are inspected for internal defects with the aid of ultrasonic waves. It is used both for welds, castings, semi-finished products, rolled products and forged products, as well as for the for measuring residual wall thicknesses on pipelines and pressure vessels. This test method is based on the time-of-flight measurement of sound waves between transmitter and receiver. By evaluating the not only the type, but in many cases also the position of indications can be determined, because different types of of indications can be determined, because different types of indications such as inclusions, cracks, shrinkage cavities and different reflective behavior for sound waves and thus cause characteristic signal patterns. signal patterns. Ultrasonic testing can also be performed under water (immersion technique). Particularly in the case of automatic testing, there is a high testing speed with a simultaneous high test density at the same time. This enables efficient and cost-effective testing.

The PMI (Positive Material Identification) or mix-up check is indispensable in order to prevent the to prevent the wrong material from being used. Particularly in incoming goods, shipping, or also in industry - for example in plant construction, toolmaking, apparatus engineering, container and pipeline construction and in foundries - this qualitative and quantitative check of the elemental composition of a sample is important. test piece is important. We work primarily with two methods - both stationary and mobile. mobile use.

The tensile test is used to determine the tensile strength, yield strength, elongation at break, necking and the modulus of elasticity. Standardized specimens are stretched to failure at a uniform rate. The flat and round tensile tests are carried out by our partners, e.g. on servo-hydraulic universal testing machines of the walter&bai ag (Switzerland) and Galbadini (Italy). By means of a with the water jet or plasma cutting method as well as automated turning (CNC), we can we can greatly accelerate the specimen preparation compared to conventional methods.

Hardness is the mechanical resistance that a test specimen offers to the penetration of another, harder test specimen. In materials testing, various classic test methods are used, such as Brinell, Vickers or Rockwell. such as Brinell, Vickers or Rockwell. Here, a test specimen with a specific geometric shape is geometric shape is pressed vertically by a defined force into the flat and sufficiently smooth surface of the test piece. surface of the test piece and then the projected surface or the depth of the permanent indentations is measured. indentations is measured. The selection of the test method depends, among other things, on the expected hardness to be expected and the nature of the specimen.

Brinell: HBW 2.5/187.5 / HBW 2.5/62.5 / HBW 5/750 / HBW 10/1000

Vickers: HV 30 / HV 10 / HV 5

Rockwell: HRC

To determine the toughness of a material, partners carry out notched bar impact tests for you. Here, the material can be tempered in the range from -196°C to +100°C. This test can be performed test can be carried out on all metallic materials. The pendulum impact testers of our partners are approved according to ISO and NIST standard. 450 Joule pendulum impact tester ISO and NIST standard Temperature range -196°C to +100°C
