Production Welding

Boron-alloyed high-strength steels are challenging for modern joining methods such as laser welding as they have a protective AlSi-layer which can reduce the strength qualities of the weld if not removed beforehand. To counteract this decrease in quality, innovative and application-specific solutions for the production of the desired weld seam structure sought for.

Pressure-hardened Steels for Car Bodies

In order to meet the increasing demands for resource preservation and the reduction of the environmental impact, the automotive industry has invested much effort to reduce the fuel consumption and emissions of the new car models. A measure which can reduce the energy consumption by about 30 % and therefore has the greatest potential, are light weight constructions. Here, the car body is the focus as it is the biggest connected element of a car and constitutes about one quarter of the entire weight. As a result, the reduction of weight in this area clearly reduces the consumption of...
