The upset formation process of rail (U71Mn) butt welding was test by thermal and mechanical simulation using Gleeble-2000 simulator. The upset pressure of rail is studied with different heat-condition.The influence of upset length, speed and current time on the weld quality is investigated.The results provide scientific foundations for settling welding procedure and improving the weld quality of rail.
