METHOD OF MANUFACTURING METALLIC WELDING WIRES, AND METALLIC WELDING WIRES FORMED THEREBY

摘要

To provide: methods of manufacturing metallic welding wires via heat-treating a metallic powder filled mold; and metallic welding wires formed thereby.SOLUTION: The subject matter disclosed herein relates to methods of manufacturing metallic welding wires and to metallic welding wires formed thereby. A method of manufacturing a metallic welding wire includes: filling a mold (100) with a metallic powder, the metallic powder filling one or more narrow elongated tubes (140) within the mold (100); and heat-treating the tubes (140) filled with the metallic powder, thereby forming a solid metallic welding wire within each tube (140).SELECTED DRAWING: Figure 1
