摩擦焊接头残余应力应变场的激光全息法研究
Research on the Residual Stresses and Strains of Friction Welding Joints
【摘要】 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
【Abstract】 Pulsed laser holography was applied to study the residual stresses and strains of friction welding joints between GH4169 and other different metals. The interference fringes pattern of the residual stresses and strains was gained by experiments and tentative analysis was made on the results of experiment.
