勾贝和滑钣在运行中,磨耗量较大。过去在厂修中采用手工堆焊效率和质量都很低。1962年初我厂开始采用自动焊,质量和效率都有很大提高。一、堆焊设备我们采用的自动电焊机是仿苏АДС-100-2型万能自动焊机。电流为400～1200安,焊丝直径3～6毫米,适用于在熔剂覆盖层下堆焊有坡口或无坡口的对接焊缝、角焊缝、直线焊缝或弯曲焊缝(但曲率不
Shell and slide sheet in operation, wear a larger amount. In the past in the factory repair using manual surfacing efficiency and quality are very low. At the beginning of 1962, our factory began to use automatic welding, the quality and efficiency have greatly improved. First, surfacing equipment We use the automatic welding machine is imitation Su АДС-100-2 Universal automatic welder. The current is 400 ~ 1200A, the wire diameter is 3 ~ 6mm. It is suitable for butt weld, fillet weld, rectilinear weld or bend weld with or without bevel welding under the flux cover (but the curvature is not
