Abstract

High speed train and high speed railway in china are booming at a very rapid pace. Relevant state departments proposed that we should "continue to develop the energy conservation and environmental protection technology system in depth for both high speed railway and high speed train" in the 13 th Five-Year Plan. As one of the most important processes in the manufacturing of high speed train bodies,welding has always been a symbol of high pollution and high energy consumption. As environmental requirements become more and more strict,the issue of solving the high pollution caused by welding has been imminent. A summary of the welding fume treatment technology was introduced in this article mainly from the points of the physical characteristics,the generation and dynamic changes of diffusion of the welding fume.
