STEEL S4 EV aims at putting high strength steels at the forefront of a new trend in electric vehicles: light vehicles with three or four wheels that comply with crash regulation and with more restrictive Euro NCAP demands. Weld joint design and welding methodologies research to maintain the material properties in the weld area, assuring robustness and long term durability. Cost-effective low-investment manufacturing will be achieved by a modular and flexible structural design: a complex 3D skeleton frame of welded tubes, bent with high accuracy using programmed laser cuts will enable the production of different vehicles sharing the same tooling.

WRIST will develop and demonstrate two flexible and cost-effective joining processes for rails, that will address the key degradation mechanisms experienced by welds in current rail infrastructure. The new processes also recognise the move of the industry toward higher speeds and axle loads and the need to increase capacity.
