Abstract
A method for automatically determining optimum welding parameters for carrying out a weld on a workpiece carries out test welds on test workpieces along test welding tracks, and at each test weld a welding parameter is changed automatically along the test welding track from a predefined initial value to a predefined final value. Each resulting test weld seam is measured along the test welding track with a sensor, and a sensor signal is received. A quality parameter characterizing each test weld seam is calculated from the sensor signal. A quality function for characterizing the test weld seam quality in accordance with the changed weld parameters is calculated from the quality parameter. An optimum quality function is ascertained, and the values for the optimum welding parameters are defined based on each quality parameter at this quality function optimum and the corresponding test weld track locations and saved.
