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。
This article describes the measurement of the residual stress of metal welded joints by the borehole strain gage method. In this method, we measured the residual stress of the Ni-based alloy welded joint of the nuclear reactor pressure vessel radial support block and the nickel-base alloy welded joint of the nuclear power plant evaporator tube plate. The measured results and existing problems are also given in the text.
