Abstract
The method concerns welding of workpieces (10) displaced relative to welding energy sources. These sources comprise at least one high-energy radiation source (11) such as a laser producing a weld seam (12) via formation of a vapour capillary (13), and at least one other energy source (14) producing an electric arc (16) which simultaneously lands within the weld zone (15). During welding the two energy sources are kept apart so that the arc (16) lands either within the joint region heated by the high-energy radiation and not cooled down to the surrounding temperature, or within the joint region not yet undergone welding. USE - For joining workpieces in the form of sheet and plate. ADVANTAGE - Working strength of welded joints is increased.
