苏联已在使用特殊合金焊剂和无涂料合金鋼絲的机械化方法,来堆焊挖掘机和拖拉机某些零件。下列一些零件堆焊层的硬度,例如:C—80型拖拉机的单边和双边滾輪(凸边和滾道),Э—505型挖掘机的履带环(滾道和导向凸部),挖掘机履带传动的主动輪和引导輪(側面和端面)等等。机械修理厂在堆焊C—80、C—100型拖拉机单边与双边滾輪的凸边和滾道时,是在堆焊装置上进行的,在这种装置上装备有ⅡⅢ—54型半自动焊机,使用АНЛ—1
The Soviet Union has used special alloy fluxes and mechanized methods without coating alloy wires to surfacing certain parts of excavators and tractors. Hardness of some of the following surfacing layers, for example, unilateral and double sided rollers (flanges and raceways) for Model C-80 tractors, track rings (raceway and guide projections) for excavators of Model-505 excavators, and excavators Crawler drive wheels and guide wheels (side and face), etc. The mechanical repair shop is performing surfacing welding on unilateral and double sided rollers of C-80 and C-100 tractors. The device is equipped with Type II-54 semi-automatic welding. Machine, using АНЛ-1
