The present invention has the same tendency to cause excessive hardening, such as cast iron, cast steel, malleable iron, sintered material, surface hardened steel, high C content steel, annealed steel, high strength steel, etc. The present invention relates to a method for welding materials (1, 2) or different materials (1, 2) using a high energy beam. The object of the present invention is to enable precision, fragile and finished parts (1, 2) to be assembled by welding, thereby providing a cost advantage. For this purpose, copper or a copper alloy containing a large amount of copper; and a plurality of basic materials to be welded together and forming a weld seam; The energy beams are used to weld a plurality of basic materials by melting in the weld seam and solidifying the melt formed by the melting. |
