The coating quality of rail vehicles is often shown in the aspects of coating appearance,richness,aging resistance,adhesion,etc.The factors that determine this outcome are not only the selection of paint types and coating process specifications,but also affected by many uncertainties of the site operating environment.Especially in the coating process,the on-site management requirements are relatively high,if any one of the links appear careless,will directly affect the quality of the coating.Therefore,this paper focuses on the on-site management of the rail vehicle body coating operation,and provides some references for the follow-up work.
