自动埋弧堆焊又叫做焊剂下自动堆焊,它是根据埋弧自动焊的原理而设计,用于旧料修复的一种工艺,它具有一系列的特点和其它堆焊工艺相比具有劳动条件好工效高、成本低、质量稳定、减少疲劳强度高等优点因此是项有推广价值的堆焊工艺。我单位是建筑、土方施工机械修理厂每年有大量的挖土机、推土机、吊车铲运机等机械的导轮驱动齿轮、轴类等因磨损需要焊补加工,长期以来我们一直采用手工堆焊的 Automatic submerged arc welding is also called automatic underlay welding. It is designed according to the principle of automatic submerged arc welding. It is a process used for the repair of old materials. It has a series of features compared with other welding processes. Good conditions, high ergonomics, low cost, stable quality, and reduced fatigue strength are the surpassing welding processes that are worth promoting. Our company is a construction and earth-moving construction machinery repair factory that has a large number of guide wheel drive gears, shafts, etc. for machinery such as excavators, bulldozers, crane scrapers, etc. Each year due to wear requires welding repairs. We have been using manual welding for a long time. of
