| Abstract: | Higher joint quality and performance good production efficiency in situ rail welding method should be developed for joint-less railway wide construction.Nowadays most ways in used are thermit welding and arc welding.In this paper,narrow gap arc welding used in rail welding is introduced,especially on our study of automatic narrow gap arc rail welding using self-shielded flux cored wire and based on arc position vision detection.Joint properties is overall better than another method thermit welding of in situ welding joint performance,can pass through the drop hammer test,tensile properties is also stronger than thermit welding,the impact performance significantly better than the currently used flash welding,gas pressure welding and thermit welding. |
