Contribution of project to standardisation

The project has developed a new method of joining metal alloys called electromagnetic pulse welding. This process uses electromagnetic forces to join work pieces, rather than heat. It does not require fluxes or shielding gases and produces no harmful smoke, fumes or slag, making it more environmentally friendly. The process is also considered less safety-critical than other joining techniques, making it more easily implementable in the industry. The project aimed to decrease the consumption of copper by partially substituting it with aluminium, with the goal of creating improved lightweight designs of copper-aluminium hybrid parts with further cost reduction and better performance. There are already standards that handle this issue, however they do not specifically include EMW but rather various welding techniques. Adaptation of these standards have been made for EMW. The process has been successfully demonstrated in three full demonstrators and the project partners are now exploring the possibility of applying the process to other multi-material joints including copper-steel and aluminium-steel alloys.
