摘    要：根据高速列车“八五”攻关项目要求，研究了铝合金材料的系列及焊接方法和工艺的选择，不同焊接材料焊接不同合金的裂纹倾向、气孔倾向，焊接接头各区性能变化，焊接接头的强韧性。

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.
