摘　　要：某轨道车辆的端墙部件在焊接完成后轮廓尺寸局部超差,无法满足设计要求导致返修,生产效率降低。针对此问题进行综合分析后发现,焊接过程中工件温度的控制、端墙板的机加工尺寸、弯曲型材尺寸和焊接顺序对端墙组成最终的轮廓尺寸存在影响。最后通过优化生产工艺,使得端墙轮廓尺寸达到设计要求。The endwalls outline size of railway vehicles are ultra-poor ＇after welding.h must be repaired because of the outline size being not accord with the design.So the production efficiency is reduced.It discoveries that the endwalls outline are ＇affected by heat input during welding, machining size of endwall panel,curved profiles size,and welding sequences after the comprehensive analysis is completed on this problem.Finally,The endwalls outline can meet with the design.
