二氧化碳气体保护焊丝防锈技术

Rust Prevention of Welding Wire Protected by Carbon Dioxide Gas

使用电子显微镜,X衍射仪,电化学等方法研究了焊丝锈蚀的原因,研制出焊丝气相防锈纸,工业试验表明其防期达3年以上。

The rusting reason of welding wire was studied by electron microscope, X-diffraction apparatus and electrochemical method. Then the vapor rust-proof paper was prepared. Industrial test result showed that the rust-proof period of the paper could be more than three years.
