  • Method and device for controlling robots for welding workpieces
    Patent number: 8338743
    Abstract: The invention relates to a method for controlling robots for welding three-dimensional workpieces, comprising the following steps: positioning and tacking profiles to a plate in order to form the workpiece to be welded, depicting the workpiece by means of a three-dimensional imaging system in the form of three-dimensional pixels, determining the geometric data of the plate and profiles, including the allocation of cutouts and final cutting shapes from the three-dimensional pixels, determining the weld seam data from the geometric data while considering the profile placement lines and the contact lines of profiles, allocating the weld seam data to parameterizable specifications for the weld plan into stored predefined movement patterns of the robot, and into commands for the control of the welding process.
