摘要/Abstract

摘要： 国际焊接学会(IIW)于2016年发布超声冲击改善焊接接头疲劳性能的推荐规范,该规范的制定主要基于轴向加载的小尺寸焊接接头的疲劳试验,没有充分考虑实际焊接结构中存在的高值焊接残余应力对疲劳延寿效果的影响。采用试验和有限元相结合的方法研究焊接残余应力对超声冲击处理焊接接头疲劳寿命的影响,结果表明,焊接残余拉应力的存在使超声冲击形成的有益残余压缩应力在疲劳服役过程中发生明显释放,进而降低超声冲击处理焊接接头的疲劳延寿效果;试件厚度方向的焊接残余应力平均值越大并且焊接残余应力在超声冲击形成的平衡拉应力区(表面向下1.5~4 mm)的值越大,残余压缩应力越容易发生释放。研究充分证实焊接残余拉应力对超声冲击疲劳延寿效果产生不利影响,并揭示其影响因素,对超声冲击处理规范的制定和疲劳评估具有指导意义。

Abstract: IIW published recommendations on high frequency mechanical impact treatment for improving the fatigue strength of welded joints in 2016, which is data obtained from available small-scale welded specimens without considering the effect of welding residual stress. Experimental and numerical method are used to investigate the effect of welding residual stress on fatigue life of welded joints treated by ultrasonic peening(UP). The results show that the existence of welding residual stress causes significant relaxation of beneficial compressive residual stress induced by UP, and further reduces the fatigue improvement. The larger are the mean value of welding residual stress along depth and the stresses in the region where self-equilibrated tensile stresses by UP exist (at depths below about 1.5-4 mm), the easier compressive residual stresses are to be relaxed. The harmful effect of tensile welding residual stress on reducing the fatigue improvement by UP is confirmed and the influencing factors are also revealed, which will provide guidance on making recommendations on proper treatment procedures and fatigue improvement assessment of UP.
