| 摘 要： | 将随焊锤击技术应用于钛合金薄板焊接应力与变形控制，分别对TC4钛合金薄板进行常规焊和采用随焊锤击技术对焊接应力与变形进行控制，结果证实，随焊锤击工艺有效地减小了薄板焊件的挠曲变形，焊缝的纵向残余应力减小到常规焊的1／10，最大焊接挠曲变形由常规焊的15mm减小为5mm。

| Abstract: | Trailing peening was adopted to control welding stress and distortion of titanium alloy thin plate.Welding stress and distortion control of TC4 titanium alloy thin plate under conventional welding and with trailing peening is performed respectively. The results show that trailing peening effectively reduces deflection of thin plate weldment. The longitudinal residual stress is decreased to one tenth of that under the conventional welding, and the maximum deflection is decreased from 15mm under conventional welding to 5mm with trailing peening. |
