CO_(2) welding
eryanghuatanq(tlboohu han二氧化碳气体保护焊(CO。welding)二氧化碳气体保护焊是以二氧化碳作为保护介质、以连续送进的焊丝为电极的熔化极气体保护电弧焊焊接方法。二氧化碳焊接设备包括电源、焊枪、CO:气体源和焊丝驱动机构。 二氧化碳气体保护焊具有成本低、抗氢气孔能力强、适合薄板焊接、易进行全位置焊等优点，广泛应用于低碳钢和低合金钢等黑色金属材料的焊接。它的主要缺点是焊接过程中产生金属飞溅。 二氧化碳气体保护焊的焊丝设计、制造和使用原则除与MIG焊有相同之处外，还对焊丝的化学成分有特殊要求:焊丝必须有足够数量的脱氧元素;焊丝的含碳量要低，一般要求C<。·11%，这是由于C02气体具有氧化性的缘故。 (田志凌)
