Why is welding wire plated copper?
The main purpose of copper wire welding is corrosion protection, because the main component of the wire is steel, and the bare leakage is easy to rust and corrosion in the atmosphere. The surface coating of copper can effectively prolong the shelf life. Furthermore, electrical conductivity can be enhanced.Welding wire is used as filler metal or metal wire welding material at the same time as conductive. In gas welding and gas tungsten arc welding, welding wire used as filler metal; in submerged arc welding, electroslag welding and MIG arc welding, welding wire as filler metal, and conductive electrode. The surface of the wire is not coated with anti oxidizing flux.
