EWM Award goes to Kai Treutler

Young scientist receives research advancement prize for his work on influencing arc stability using thin-film coated wire electrodes.

Kai Treutler has won this year’s “Physics of Welding” EWM Award, which carries prize money of 30,000 euros. The research advancement prize from Germany’s largest manufacturer of arc welding technology was presented at the DVS EXPO in Nuremberg. Sponsored by EWM AG and awarded this year for the fourth time in conjunction with the German Welding Society DVS, the prize helps young scientists turn their welding vision into reality. Through this year’s award, EWM will help the winner carry out his research work on “Influencing arc stability using thin-film coated wire electrodes”. In his speech at the awards ceremony, Prof. Dr. Steffen Keitel, director of SLV Halle GmbH, praised the young scientist’s outstanding approach which opens up highly interesting prospects in this area of welding.

In his research work, Kai Treutler, a scientific assistant at the Institute of Welding and Machining at Clausthal University of Technology, focuses on characterising arc influences through coated solid wire electrodes. He is planning to develop an arc-stabilising coating system that does not affect mechanical or technological properties. While the positive influence of the arc through, for example, stick and flux cored wire electrodes is well-known, such a concept for solid wire electrodes has been almost totally lacking up to now.

Thin coating increases strength of weld metal
With his research work, the winner of the EWM Award plans to harness arc-influencing effects achieved with thin-film coatings made from metallic and ceramic materials of various compositions and utilise them for solid wire electrodes. His initial investigations have revealed that coatings of 2 to 15 micrometres can have a significant impact on the mechanical properties of the weld metal and penetration characteristics. This enables the strength of the weld metal to be increased by 50% compared to an uncoated wire. The research, now supported from EWM, will drive forward the development and adaptation of various coating systems for customer and application-specific requirements with regard to arc stability, droplet transfer and penetration.

The EWM Award, which is presented every two years, focuses on the discovery of new ideas and innovative scientific approaches in arc, laser, electron beam and hybrid welding procedures. The prize is awarded by an independent jury. Once the research work has been completed, it will be published in conjunction with the DVS. As a result, this year’s winner not only benefits from support for his research work, but can also look forward to raising his profile further among experts in his field in future.
