Increasing challenges to match the requirements of lightweight design and cost-effective production technologies - including the trend to be more design-derivative and to lower lot size - need easy and flexible production processes, and laser remote welding technology can be one solution. Lightweight concepts for automotive structures using metallic hybrid concepts, like aluminum-steel structures as well as local adapted strength distribution, are becoming more and more interesting. Controlled laser remote processes can be used for direct joining of aluminum-steel T-joints and local laser-hardening tracks improve the crash performance of steel profiles significantly.
