Carbon dioxide gas shielded arc welding is a welding method for the protection of the gas is carbon dioxide gas, the welding method. In the application of simple, suitable for welding and full welding. Not have wind in welding, suitable for indoor operation. Because of its low cost, easy to produce carbon dioxide gas, widely used in enterprises of all sizes
Carbon dioxide gas shielded arc welding (referred to as CO2 welding) of the protective gas is carbon dioxide (sometimes using CO2 + O2 gas mixture). As the carbon dioxide gas thermophysical properties of 0 special effects, the use of conventional welding power source, the Welding Wire  ends to form the molten metal can not balance the axial free transition, and usually requires the use of short burst of droplet necking off, therefore, and MIG welding free transition compared to splash more. However, if the use of high-quality welding machine, select the appropriate parameters, can be very stable welding process, so that splash down to a minimum. As used in protective gas prices low, with short transition weld good, coupled with the oxygen-containing agents can be wire-free high-quality welded joints within the defect. So this welding method has become the most important black metal welding methods.
Stainless Steel Welding Wires is caused by the current heat generated by the arc melting.
