摘要
基于铸件的焊接规范和工艺过程,因其材料的特殊性而要求比较严格,特别是大型铸件的修补,如采用热焊法则比较困难。谨以广东肇庆化工机械厂的剪床(Qll-6.3X2000)中的压板机构(铸铁材料)裂纹的冷焊修复为例,论述了大型铸件的冷焊修补过程,与同行共同探讨。
Based on Casting welding specification and process, due to its special material are many stringent requirements, especially for large casting repair, if using hot wending ru difficult. The author takes the Guangdong Zhaoqing Chemical Machinery Factory shears（ plate mechanism（cast iron） in cold welding repairing crack as an example. The paper ma cold welding repair process of large castings. proporty, there le, it＇ll be very QII-6.3X2000） inly shows the
