Background

At present, in the process of capital construction, carbon dioxide arc welding is required to be used for welding the steel bars in the capital construction, and is called carbon dioxide arc welding. The shielding gas is carbon dioxide (sometimes a mixed gas of CO2+ Ar) and is mainly used for manual welding. Due to the special influence of the thermophysical properties of carbon dioxide gas, when a conventional welding power supply is used, the molten metal at the end of a welding wire cannot form balanced axial free transition, and a short circuit and molten drop necking and bursting are generally adopted, so that the splashing is more compared with the free transition of MIG (metal-inert gas) welding. If a high-quality welding machine is adopted, the parameters are selected properly, a stable welding process can be obtained, and splashing is reduced to the minimum degree. Because the used protective gas is low in price, the weld joint is well formed during short-circuit transition, and a welding wire containing a deoxidizer is used, so that a quality welding joint without internal defects can be obtained. Therefore, the welding method becomes one of the most important welding methods for ferrous metal materials; but at present when using carbon dioxide arc welding, move the welding machine to carbon dioxide because of the too big will not stop in place, the steel of placing simultaneously in the place is too much, the weight of carbon dioxide welding machine is overweight to be removed inconveniently, and the carbon dioxide hose hangs on steel along with the carbon dioxide welding machine at the in-process that removes easily, causes very big inconvenience to using the carbon dioxide welding machine, and the carbon dioxide jar that carbon dioxide arc welded simultaneously also is located the place, has caused very big potential safety hazard for the welding.
