Collaboration between TRUMPF, Fraunhofer ILT, DESY and Hereon provides the most detailed of insights into laser welding processes to date thanks to the particle accelerator
High-performance electronics are in every e-car and, as a key technology, ensure the best performance of the battery and motor. The Hamburg researchers, together with the high-tech company TRUMPF and the Fraunhofer Institute for Laser Technology ILT, have now investigated the laser welding processes that are used in the manufacture of e-cars. TRUMPF, Fraunhofer ILT, DESY and the Helmholtz Center Hereon each contributed their highly specialized knowledge of X-rays, laser sources and welding processes. As a result, insights that remain invisible to the eye and even to microscopes have now been achieved for the first time. The result: When a laser with green wavelength is used, far fewer rejects are produced than with other laser welding processes. Car manufacturers save raw materials and thus contribute to more sustainable manufacturing.
