表面堆焊技术在汽车修理中的应用发动机缸体、变速器壳体、液压油缸等零件的特点是质量大，形状复杂，造价高，当其发生裂纹或其它损坏时，若不及时修理，将会使整个总成报废，造成极大的浪费。另有一些零件，如销子、齿轮等，由于单价不高，当它们磨损失效时，往往直接更换新件，长此以往，必然消耗巨大，其实它们也是可以修复再利用的。 表面堆焊技术是零件表面修复技术的一种，就是利用手工电弧焊对受损零件的表面加以堆焊或修补，或经过机床加工，恢复零件的原有尺寸，必要时通过热处理改善其性能。 评定修复层的主要指标为：1)修复层与基体金属的结合强度；2)修复层的耐磨性和耐腐蚀性；3)修复层对零件疲劳强度的影响。上述3项指标中结合强度是评定修复层质量的首要指标。 一、铸铁件的修复 发动机缸体属于非易损基础件，一般寿命较长，除遇意外事故，都能用至机器报废。但有时也会发生破损、裂纹或曲轴主轴承座孔失圆变形等情形，在这种情况下更换整个缸体无疑会造成巨大浪费，因此必须想办法加以修复。 实例1：一台上海产6135发动机，由于冬季在室外停放时忘记放水，缸体气缸套处开裂一道长约4cm的裂纹，运用手工电弧焊修复工艺如下： 1)焊条：选用铸612铜铁焊条，焊条直径3.2mm，焊后不进行机械加工。 2)清除污物：将裂纹周围清洗干净，包括油污、铁锈，裂纹深处的油污和水用氧——乙炔火焰加热，直到不冒烟为止。 3)修整裂纹：在裂纹两端钻φ3mm的止裂孔。为了增大结合强度，沿裂纹方向用手砂轮开出U形坡口，坡口开度120°，深4-6mm。坡口两侧25mm以内用钢丝刷打光，露出金属表面。 4)施焊：使缸体裂纹成水平位置放置，运条方向由两端向中间进行，待整条裂纹焊补完毕后，再焊两端的止裂孔。焊接速度为3.2-3.5mm/s，电流为80-110A。 实例2：一台康明斯发动机，缸体曲轴主轴承第二、三座孔同轴度误差达0.13mm。由于轴承座孔上有轴瓦覆盖，仅起支承及散热作用，焊接强度要求不高，但精度需达到一定标准，考虑采用钎焊修复轴承座孔，然后在搪瓦机上加工成型。 1)钎料：由于曲轴主轴承处是受力部位，黄铜的结合强度在200mpa以上，因此选用黄铜。
