补充资料：堆焊
在金属零件表面熔敷耐磨、耐腐蚀或其他特殊性能的金属层的焊接方法。堆焊层可显著改善工件的工作性能或提高其使用寿命，还可以节约贵重金属材料，降低生产成本。常用的堆焊材料有各种钢、合金铸铁、镍基合金、钴基合金和铜合金，以及碳化钨与适当基体金属组成的复合材料等。堆焊材料根据工件工作时的磨损类型、介质性质和工作温度来选择。堆焊材料按其加工性能的不同可以轧成丝或带，铸成条或制成粒状粉末，制成药芯焊丝或涂药焊条。几乎所有的熔化焊工艺方法都可以用于堆焊，但应尽可能选用母材熔深较浅、填充材料熔化较快、经济性好的工艺方法。常用的有手工电弧堆焊、丝极或带极埋弧堆焊和等离子弧堆焊等。堆焊广泛用于在钢制工件上熔敷各种金属和合金，例如在原子能压力容器内壁堆焊不锈钢，在高炉料钟表面堆焊高铬合金铸铁，在热轧辊表面堆焊热模具钢，在柴油机排气阀表面堆焊镍基或钴基合金，以及在机械修理中修复各种被磨损的轴等。
