    Laser welding for crack-free EV battery housings

    What is this about?Car and aircraft makers join metal parts by melting and fusing them together — that’s welding. Traditionally some welds need a separate “filler” wire (like extra metal solder) to make a strong seam. Fraunhofer IWS has shown a laser method that controls the molten metal so precisely that the filler wire isn’t…
