Magnetic pulse welding is a new, very innovative but nearly unknown production process. The working principle of the welding process is based on the use of electromagnetic forces to deform and to weld workpieces. Since this sophisticated welding process doesn't use heat to realise the weld, it offers important advantages with regard to the conventional welding techniques!

SOUNDWELD investigates a new promising real-time non-destructive examination technique for welding processes, based on acoustic emission during the weld cycle. The acoustic emission technique is based on the detection and conversion of high-frequency elastic waves into electrical signals. Acoustic emission monitoring (AEM) is currently being used for the surveillance of industrial processes or structures. In this project, the application of this technology is expanded towards welding processes.

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.

The STWIN project will develop a flexible friction stir welding (FSW) system capable of automatically fabricating complex 3D structures, for a variety of joint configurations, and for a range of steel grades and thicknesses used in the metal construction, automotive and transport sectors.

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.
