用脉冲激光全息方法对 GH416 9及异种金属材料摩擦焊接头残余应力应变进行了研究探讨 ,通过实验 ,获得了其焊接接头残余应力应变场的干涉条纹图 ,并对实验结果进行了初步的分析讨论

By means of pulsed laser holography method, the residual stress and strain of GH416 9 and dissimilar metal friction stir welding joint were studied and discussed. The interference fringe pattern of residual stress and strain field of welded joint was obtained through experiments. The experimental results were analyzed and discussed
