Innovative surface crack detection for the aerospace industry

In materials testing, the detection of the smallest material defects is crucial for the safe operation of aerospace components. 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 aerospace 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 been increasingly focusing on the development of magnetization equipment for crack detection on components for aircraft manufacturers.

Furthermore, UV LED technology for the inspection of large components, weld seams and turbine blades of aircrafts is being continuously developed. Also, there are significant new developments in the field of non-hazardous and eco-friendly 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-held magnets to powerful high-current generators with pulse magnetization, and PLC-controlled MPI-benches.

The well-known Dykem® products supplied by HELLING are used with great success to monitor the properties of gear components during operation and to check the load-bearing capacity of gears.

The Hamburg Training Centre of the German Society of Non-Destructive Testing (DGZfP) / 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.
