Method for the plasma, laser or electron beam welding of identical or different materials with a tendency for excessive hardening, with copper or a copper alloy as a filler material

摘要

A method for welding identical or different materials with a tendency for excessive hardening. The method uses a high-energy beam to melt, in a weld seam, copper or an alloy having a high copper content and a basic material or materials such as cast iron, cast steel, malleable iron, sintered material, case-hardened steel, steel with a high C content, annealed steel, high-strength steel, and the like. The use of copper provides a weld with a lower melting point.
