The original idea stems from the 1920s of CO2 welding process, weld pores problem is not resolved, however, causing the CO2 welding can not be used. Until the early 1950s, the development of Welding Electrode Materialtechnology to solve the problem of CO2 Welding Wire Manufacturers, developed a series of wire in the Si-Mn, which makes CO2 welding process to obtain a practical value. After that, according to the performance of structural materials, have appeared in wires of different groups of ingredients, to meet the diverse needs of CO2 welding.
CO2 welding process utility into society brought great wealth, on the one hand, because the CO2 gas is inexpensive, easy to obtain, on the other hand is due to the high CO2 welding of metal deposition efficiency, semi-automatic CO2 welding, for example, its efficiency manual arc welding of three to five times.
