In the current transformation of the automotive industry, joining technology is once again at the centre of technical discussions in car body construction: The integration of battery systems, fuel cells or hybrid propulsion systems into the car body brings with it considerable new challenges for joining technology. At the same time, car body development is under considerable cost pressure these days, which primarily entails demands for efficiency improvements, lean development processes as well as less complexity and greater flexibility in production. Meanwhile, the question of comprehensive sustainability and climate neutrality in automotive production is also becoming increasingly important.
