During welding with high output power, the gaps between the pieces being joined may not exceed a maximal gap width. A process for laser beam welding is provided, which on the one hand ensures maintaining (not exceeding) a maximal gap width between the sheets and on the other hand makes possible a maximal utilization of the achievable welding speed. The sheets, prior to welding, are first spot welded, wherein they are clamped only during this spot welding in order to ensure the maintenance of a maximum gap width.

A vehicle-useful, high-resolution 3D-detection of the environment of a street vehicle with environment scanning sensors is not possible today. Depending on application the first commercially available vehicle integrated systems may be a comprise between resolution of the sensors and size of the sampled area. With the inventive two dimensional distance resolution sensor device it becomes possible, in contrast to those which are known, to produce a system which, installed in a street vehicle, detects and preferably processes complex dynamics scenarios such for example street traffic, from the prospective of the active dynamic moving vehicle. Therein a three dimensional image of the environment is produced using a distance sensor, which produces a two dimensional distance profile (depth profile), and on the other hand, using a data processing and a storage unit, which process and store sequential distance profiles and sequence a series of distance profiles into the three dimensional image of the environment.

The invention relates to a process for the control of the position of workpiece and tool with a robot in a production machine. The objective of the invention is to reduce non-productive secondary processing time during the processing or measuring of a workpiece with a robot. The invention consists of a process for the control of the position of workpiece and tool with a robot in a production machine in which the workpiece () is positioned relative to the tool (), () and during a continuous movement of the workpiece () with a tool (), () at the processing location of the workpiece () a process takes place, and the tool (), () is moving during the process synchronously to and in the same direction like the workpiece () and during the continuous movement of the workpiece () the tool (), () is moved to and positioned in another processing location.
