二氧化碳保护焊是以二氧化碳作为保护气体,依靠焊丝和焊件之间生产的电弧来熔化金属的焊接技术。它具有成本低,质量好,生产率高,抗锈能力强等优点。二氧化碳气体保护焊不仅用于低碳钢、低合金钢、不锈钢等材料的焊接,而且还用于磨损零件如曲轴,锻模的堆焊、铸钢件等缺陷的补焊。用于汽车、机车、造船以及航空等工业部门。送丝机是二氧化碳气焊机的主要构件。我厂职工在毛主席革命路线的指引下,组成工 Carbon dioxide welding is a welding technique that uses carbon dioxide as a shielding gas and relies on an electric arc produced between the wire and the weldment to melt the metal. It has the advantages of low cost, good quality, high productivity, strong anti-rust ability. Carbon dioxide gas shielded welding is not only used for low carbon steel, low alloy steel, stainless steel and other materials welding, but also for wear parts such as crankshaft, forging die surfacing, cast steel and other defects welding. For cars, locomotives, shipbuilding and aviation and other industrial sectors. Wire feeder is the main component of carbon dioxide gas welding machine.
