目前,最新研制成功的带极电渣堆焊,无论从所需的设备和受控参数的数量、类型等方面与带极埋弧焊相比较都基本相同,并容易掌握。因此,就相对热输入和堆焊厚度来看,带极电渣堆焊能达到提高熔敷率和生产率的效果且母材的稀释率很低。如果在含碳量0.20％的低碳钢母材上堆焊一层,就能达到含碳量很低的不锈钢(最大含碳量为0.03％)。该 At present, the newly developed electrodeposited ESR welding is basically the same as that of the SAWM in terms of the number and type of required equipment and controlled parameters and is easy to grasp. Therefore, considering the relative heat input and surfacing thickness, the ESR surfacing can achieve the effect of improving the deposition rate and the productivity, and the dilution rate of the parent material is very low. Stainless steel with a low carbon content (up to 0.03% carbon) can be achieved by surfacing a layer of low carbon steel with a carbon content of 0.20%. This
