摘　　要：应用共晶点左移理论研制以奥氏体和铁素体为基体的两种类型铸铁冷焊焊条，具有较窄的白口区和较高的白口断续率，可以代替国家标准相应类型铸铁焊条。This paper introduces the development of two types of cast iron cold-welding electrodes which are based on austenite and ferrite by means of the theory of eutectic point left movement.Having narrower white cast zone and higher white cast uncontinuous rate,the electrodes can be used as a substitute for the equivalent conventional cast iron electrodes.During the course of the development,the application of the theory of eutectic piont left movement is further analysized.
