Title: METHOD AND DEVICE FOR WELDING JOINT PARTNERS
Abstract:
The invention relates to a method and to a device for welding at least two joint partners (20, 22) to form a welding seam using both a laser beam and an electric arc beam (18), which are provided by a hybrid welding device (10). According to the invention, to achieve a better energy input in the joint region and an optimised welding process on the gap to be bridged between the joint partners to be welded, a single focal point (32) of the laser beam (18) is focused onto the joint region (26) and the focal point is adjusted relative to the displacement movement of the hybrid welding device (10) and transverse to and/or in the direction of displacement (11) of the hybrid welding device.
