WELDABILITY OF ALUMINIUM ALLOYS AND PROPERTIES OF WELD JOINTS
（South-western Jiao Tong University, Chengdu 610031）
Abstract:According to the requirements of high speed trains in the key program of the 8th Five-year plan of China, the choice of Al-alloy used for high-speed trains and its matching with welded material and welding technology were studied. In addition, its weldability, change of properties in each zone of weld joints and the strength and toughness of the welding joint were also studied.
Key words: high-speed trains welding of aluminium alloy strength and toughnees weld joints
