铸铁冷焊在农机修理中应用日益广泛,它与过去常用的气焊(热焊)相比有以下优点:①设备材料简单,工艺技术容易掌握,一般区、社农机厂(站)均可以开展;②修复面广,即使是比较复杂的铸件也可以焊接;③由于铸件不需加热,可减轻焊工劳动强度;④只要工艺操作得当,可用一般纯碳钢焊条代替价格昂贵的不锈钢焊条,降低成本。 Compared with the conventional gas welding (hot welding), the cast iron cold welding has the following advantages: ① The equipment is simple and the technology is easy to master; ② repair a wide range, even more complex castings can be welded; ③ because the casting does not require heating, can reduce the labor intensity of welders; ④ as long as the process is properly handled, the general use of pure carbon steel electrodes instead of expensive stainless steel welding rod, reduce costs.
