摘　　要：综述了CO2焊接工艺优缺点及其原因;强调了MAG焊工艺优于CO2焊工艺,如它能减少熔滴过渡过程中的飞溅并提高焊缝金属冲击韧性;列举了MAG焊在重要构件,如管线钢等焊接方面的应用实例。The merits and defects of CO 2 welding and their reasons are introduced,and the fact that MAG welding is superior to CO 2 welding is emphasized,such as reducing spatter during metal transfer and increasing impact toughness of weld metal ,some typical application cases such as MAG welding can be used for welding pipe line steels are also introduced.

关 键 词：CO2焊 MAG焊 保护气体
