Description

technical field [0001] The invention relates to the technical field of copper alloys, in particular to a copper alloy welding wire, a preparation method and an application. Background technique [0002] The birth and development of comprehensive mechanized mining with hydraulic support as the main equipment is a major revolution in the history of coal mine production. The face of production has completely changed. Copper melting technology on the inner wall of hydraulic support column oil cylinder, as an emerging oil cylinder repair technology in recent years, adopts CMT (cold metal transition technology) welding method to melt copper alloy welding wire to obtain wear-resistant and corrosion-resistant copper alloy layer combined with base metallurgy , and has the thermal and electrical conductivity of copper, so as to improve the life of the hydraulic support. As the working conditions of the hydraulic support become worse and the working resistance increases, the requirem...
