Abstract Welding is an important processing in manufacturing industry, especially in the equipment manufacturing industry, there is about 45% steel in the world used for welding structure. Welding technology has been widely used in ship-building, automobile, railway, oil, and other industrial production department, which plays an important role in promoting the development of industry and products and promotes the development of national economy,. In 21st century, science and technology develop rapid, efficient- energy welding technology become more and more attentioned, especially in the shipbuilding industry. New welding materials, welding technology or new welding equipment is in urgent need for high efficiency welding requirements on the market. In thie paper,experimental study about high deposition rate and energy saving which are two main characteristic of Tri-Arc welding was carried out. We respectively use Tri-Arc welding systems and Twin-wire MIG welding to do welding experiments on 40mm thick slab,12mm plate and 2mm sheet,compared with the difference of deposition rate in the same base metal hear input and the difference of power consumption per ton of deposited metal in the same total welding current,and some analysis on the energy-efficient mechansim of Tri-Arc welding were made. Firstly by Tri-Arc welding system for 2mm plate, 12mm plate and 40mm welding testing plate, compared Tri-Arc and double wire MIG welding deposition rate differences and save energy. Results are displayed using the Tri-Arc system than ordinary Twin-wire MIG welding welding when welding different thickness of base metal deposition rate increased by about 30%, about its consumption of electricity decreased by 20%. And analysis of the reasons for these differences are mainly m-arc welding current shunt function and speed up the melting of the wire, metal transfer contribute to.
