钎焊铜及铜合金、钢及不锈钢等 | 2)锰(Mn)锰在钢中是一种较好的合金剂，随着锰含量的增加，其强度和韧性会有所提高。在焊接过程中，锰也是一种较好的脱氧剂，能减少焊缝中氧的含量。锰与硫化合形成硫化锰浮于熔渣中，从而减少焊缝热裂纹倾向。因此一般碳素结构钢焊芯的含锰量为0. 30%～0. 55%，焊接某些特殊用途的钢丝，其含锰量高达1 ．70%一2. 10%。 |

钎焊铜及铜合金、钢及不锈钢等 | 二、保护焊接熔池。焊接过程中，空气中的氧、氮及水蒸气浸入焊缝，会给焊缝带来不利的影响。不仅形成气孔，而且还会降低焊缝的机械性能，甚至导致裂纹。而焊条药皮熔化后，产生的大量气体笼罩着电弧和熔池，会减少熔化的金属和空气的相互作用。焊缝冷却时，熔化后的药皮形成一层熔渣，覆盖在焊缝表面，保护焊缝金属并使之缓慢冷却、减少产生气孔的可能性。 |
