Abstract:It is necessary to reduce the weight of railway vehicle in order to reduce its ienergy consumption.Aluminum alloy body of railway vehicles is a effective measure to reduce body weight.In this paper,the current state of aluminum alloy application and its corresponding welding technique for railway vehicles in Japan were summarized.The structure characteristics,material types and welding method used in four generations of aluminium alloy railway vehicle was introduced.The trend of welding technique and material used in aluminium alloy body of railway vehicle were discussed.Based on analyses,the paper pointed out that the application of 7N01 alloy containing more zinc wiould be limited,whereas the application of 5000 and 6000 series aluminum alloy would become broader.On the other hand,Friction stir welding would become a main welding technology in railway vehicle manufacturing,and the application of laser welding,especially in remote welding,is also expected.
Keywords:aluminum alloy  railway vehicles  welding
