摘　　要：采用氩弧焊工艺焊接的钛合金筒形焊接件,存在壁厚薄、直径大、制造精度要求高等特点。长期的经验积累以及分析认为,零件的制造过程中存在着两个关键点:筒形件热成形回弹的解决以及焊接变形的控制。在生产过程中,运用了使用有限元软件计算回弹补偿后的模具型面的方法以及多种焊接变形控制措施,使得零件最终生产后满足各项制造技术要求,取得了良好的效果。The characters of cylindrical work- piece of titanium alloy welded by argon arc welding include thin-walled, large-diameter and high accuracy requirement. Based on long-term accumulation of experi- ence and analysis, there are two key points for the parts manufacturing technology analyzed and proposed： the so- lution of springback of cylindrical workpiece＇ hot forming and the method of controlling welding distortion. In the production process, a calculation using the FEM software after springback compensation method mold surface and a variety of welding deformation control measures are applied. The parts produced finally satisfy all the require- ments of manufacturing technology.
