Modern cars are confronted by a number of demands and requirements. These demands for further improvements of active or passive safety, buckling strength, ease of driving or operating and energy expenditure makes optimizing the car's weight now as in the past as an important factor in designing and constructing a car. In comparison to competitive materials high strength steels (HSS) as High Strength Low Alloys (HSLA), phosphorised or bake-hardening steels and dual-phase steels are more qualified to advance the passive safety of a car body. For a future application of laser beam welding of these materials in the car-body production, investigations in the materials behaviour while the welding process and the 3-dimensional welding of thin steel sheets were carried out. The last task was devided up into investigations on joining flat sheets in any position, welding of structural elements and actual components. A further field deals with developments in the peripheral equipment. Not only a concept for supplying process gas, but also a distance measurement and control system was developed. Furthermore a ultrasonic testing method was developed and optimized, which allows examining welds. Although laser beam welding is now being established as a joining technology and its use is seen as a very important factor in competition in European and worldwide markets, there are still many unsolved questions concerning the process itself, interaction with the material and adaptive processing techniques.
