Alloyed ultra-high strength steels

New ultra-high strength steels provide new lightweight opportunities and improve crash properties in future car bodies. Understanding the joining process as well as the response of the base materials on heat input is in order to create designs exploiting the full potential and fulfill the extensive requirements. The following paper makes a contribution for a safety applying of new materials into the car body manufacturing process. Furthermore, it supports the user with laser-beam joining recommendations for a verified weldability.
