本文介绍铸铁件坡口表面进行镍拉毛和涂敷镍基自熔性合金粉末后,再采用CO_2保护细丝焊接的新工艺。该工艺况获得与纯镍焊条相当的补焊质量,因而经济效益显著。
This paper describes the surface of the cast iron grooved nickel coating and coating of nickel-based self-fluxing alloy powder, and then use CO_2 protective filament welding new technology. The process is obtained with pure nickel electrode repair welding quality, and significant economic benefits.
