The company HELLING GmbH based in the north of Germany is a leading manufacturer of systems, devices, reference blocks/test panels and test equipment for non-destructive material testing (NDT).
In materials testing, the detection of the smallest material defects is crucial for the safe operation of wind turbines. As a leading company in the field of non-destructive testing, HELLING GmbH is continuously working on making surface crack detection more reliable and cost-effective.
As a long-standing partner of the wind industry, HELLING GmbH supplies high-quality systems, equipment, and consumables for non-destructive testing. In addition to the widely used HELLING magnetic particle suspensions, state-of-the-art UV-LED technology, and the well-known penetrant testing systems, HELLING has increasingly focused on the development of magnetisation equipment for crack detection on components for the wind industry. Furthermore, UV LED technology for the inspection of large components, weld seams and gears of wind turbines is being continuously developed. Also, there are significant new developments in the field of non-hazardous and ecologically compatible testing media. For example, a new type of dry concentrate of magnetic particles has been developed for the preparation of water-based suspensions. There are also significant innovations in the field of systems and equipment for crack detection: From ergonomic hand magnets to powerful high-current generators with pulse magnetisation, and PLC-controlled magnetic benches. The well-known Dykem® products supplied by HELLING are used with great success to monitor the properties of gear components in operation and to check the load-bearing capacity of gears. The DGZfP Training Centre Hamburg/ HELLING offers qualification courses in most NDT procedures such as VT, PT, MT, RT and UT according to DIN EN ISO 9712, as well as in the training of inspectors (PT, MT and UT) according to DIN 54161 and in radiation protection. A well-equipped optical measuring laboratory, complex test series and certification according to DIN EN ISO 9001 make a decisive contribution to ensuring a high-quality standard and the further development of our products.
