METHOD FOR SHAPING MATERIALS WITH PLASMA-INDUCING HIGH-ENERGY RADIATION

摘要

The invention relates to a method for shaping materials with plasma-inducing high-energy radiation, especially laser radiation. According to said method, the momentary intensity of the plasma radiation is measured in several place s on a steam capillary. In order to be able to carry out the method for lower workpiece thicknesses with good welding results, the shapes of two maximum intensity regions (10, 12) located at a distance from each other, or of another electromagnetic beam emitted from the steam capillary, and the shape of a minimum region (11) that can be formed between these two regions with extreme values are determined using a measuring technique, the so determined shapes of the regions with the extreme values are compared with predetermine d region shapes, and the material processing operation is controlled in dependence on the deviations of the determined shapes from the predetermined region shapes.
