Abstract (en)
[origin: WO2005030423A1] The invention relates to a method for welding identical or different materials (1, 2) with a tendency for excessive hardening, such as cast iron, cast steel, malleable iron, sintering material, case-hardened steel, steel with a high C content, annealed steel, high-strength steel etc., said method using a high-energy beam. The aim of the invention is to be able to assemble highly precise, delicate, finished elements (1, 2) by means of welding, and this in a cost-effective manner. To this end, copper or an alloy with a high copper content, and the material(s) to be welded defining the weld seam, are melted in the weld seam by means of the high energy beam, and the material(s) are welded by the solidification of the melted mass formed.
