焊条药皮是指涂在焊芯表面的涂料层。药皮在焊接过程中分解熔化后形成气体和熔渣,起到机械保护、冶金处理、改善工艺性能的作用。药皮的组成物有:矿物类(如大理石、氟石等)、铁合金和金属粉类(如锰铁、钛铁等)、有机物类(如木粉、淀粉等)、化工产品类(如钛白粉、水玻璃等)。焊条药皮是决定焊缝质量的重要因素,在焊接过程中有以下几方面的作用:

焊接碳钢及低合金钢的焊芯, 一般都选用低碳钢作为焊芯,并添加锰、硅、铬、镍等成分(详见焊丝国家标准GB1300一77)。采用低碳的原因一方面是含碳量低时钢丝塑性好,焊丝拉拔比较容易,另一方面可降低还原性气体CO含量,减少飞溅或气孔,并可增高焊缝金属凝固时的温度,对仰焊有利。加入其他合金元素主要为保证焊缝的综合机械性能,同时对焊接工艺性能及去除杂质,也有一定作用。
