Copper plated welding wire is a layer of copper coated on the surface of ordinary welding materials. The main function of this layer of copper is to prevent rust on the surface of the welding wire, reduce the friction coefficient, lower the wear on the conductive nozzle, improve the service life of the conductive nozzle, and also reduce the contact resistance between the conductive nozzle and the welding wire.

The process flow of copper plated welding wire mainly includes the following steps: wire laying, wire brush mechanical film breaking, vibration sand washing, electrolytic alkali washing, water washing, electrolytic acid washing, water washing, chemical copper plating, water washing, passivation (selective addition), hot water washing, drying, sizing polishing, and wire winding. In this process, it should be noted that the surface roughness of the welding wire substrate will affect the bonding strength of the copper plating layer, so it is necessary to repair the mold and reduce its inner hole roughness. In addition, if there is oil stains on the surface of the welding wire before entering the plating tank, it is also necessary to strengthen pre-treatment and clean it with running water.

Overall, copper plated welding wire is a specially treated welding material that can improve welding quality and efficiency, reduce equipment wear, and contribute to environmental protection.
