摘　　要：本文介绍了用钻孔应变计法测定金属焊接接头的残余应力的测量方法。用此方法我们测定了核电站反应堆压力容器径向支承块镍基合金焊接接头和核电站蒸发器管板镍基合金焊接接头的残余应力。测得的结果和存在的问题也在文中给出。The hole-drilling strain gage method for determing residual stressed of the metal welding joints is introduced in this paper. Using the method we determine the residual stressed of nickel alloy welding joints on radial supports of atomic power station reactor pressure vacuum and plates of evaporator-tube in atomic Power Station. The results and present problems are reported in this paper.
