EHLA: for demanding applications

EHLA (Extremes Hochgeschwindigkeits Laserauftragsschweißen) is a new version of laser cladding. Hornet has been involved at an early stage in the development of EHLA by the Fraunhofer ILT (D). With this EHLA process the coating can be applied much faster and more precisely. Every hour the installation applies up to 1 m2 of material on a rotationally symmetrical component. With welding speeds of up to 500 meters per minute. That is a factor of 10 more than with conventional laser cladding.

Processing time

A second important difference is that the layer thickness is only 25 μm to a maximum of 400 μm. This also contributes to a considerable short production cycle. In conventional laser cladding, the minimum layer thickness is 500 μm, a considerable part of which is removed with CNC turning.

Chrome 6 replacement

The first applications of EHLA can be found in offshore components. By applying an Inconel 625 wear-resistant layer, a chrome coating can be replaced in many applications, with wear-resistant properties that are at least as good, if not better.

Hybrid coatings

EHLA is constantly being developed. An example are so-called hybrid coatings: an extremely wear-resistant layer is applied on top of the anti-corrosion coating. Thanks to the close cooperation with the Fraunhofer ILT and powder manufacturers, Hornet Laser Cladding remains involved in future developments. This ensures that customers always work with state-of-the-art laser cladding technology.
