比较电振动堆焊、熔剂层下堆焊、金属喷涂和镀铁等修复工艺,电接触堆焊的优点是:生产率高,金属烧损少(<50%),热影响小(仅0.3毫米),可在各种钢和铸铁基体上堆焊黑色或有色金属。下面简介一种小直径零件的电接触堆焊工 The advantages of electrical contact welding are: high productivity, less metal burnout (<50%), less thermal impact (only 0.3 mm) compared to the electrical vibration welding, flux underfill, metal spray and iron plating repair processes. , In a variety of steel and cast iron substrate black or non-ferrous metals. The following is a small diameter parts of the electrical contact with the welder
