Cable-type welding wire arc welding

A novel welding method termed cable-type welding wire (CWW) arc welding is proposed in this study, wherein the CWW is used as a consumable electrode. The CWW is composed of seven welding wires, with one welding wire in the center and the other six wires distributed uniformly around the center wire. During the welding process, only one welding power source, one wire feeder and one welding torch are used. The deposition rate can be greatly improved due to the simultaneous melting of the seven wires. The six peripheral wires rotate around the center wire, forming a self-rotating arc, which improves the welding quality. The deposition rate of CWW CO2 welding improved by 40% relative to that of single-wire CO2 welding under the same conditions. The energy saving of CWW submerged arc welding (SAW) improved by 25% relative to that of single-wire SAW under the same conditions. CWW arc welding is an innovative welding method with high efficiency, energy saving, simple equipment, welding automation and high welding quality, which has a wide range of market prospect.
