摘　　要：讨论了球封头与筒体对接接头TOFD检测时如何建立模拟等腰三角形,以适应仪器内置深度定位计算程序。介绍了显示深度与实际深度的修正计算方法,并通过对显示深度测量值与计算值的误差计算,验证了上述计算方法的正确性。This paper firstly discussed how to set up simulated isosceles triangle in TOFD detection of butt joint between spherical head and barrel to adapt to the default calculation program of depth location.We proposed the modified calculation method between the measured depth and the actual depth,and verified the correctness of the above calculation method by calculating the error between the measured depth and the calculated value.
