摘要
介绍半球对接焊缝超声探伤的声程定位方法。采用作图法确定水平距离与里波声程的对应关系,从而对回波信号进行分析并对缺陷进行定位。
Ultrasonic flaw location in semisphere butt welds by sound path method is described. The corre-sponding relationship between horizontal distance and inner wave sound distance is determined by drawing and flaws are located by analyzing reflection signals.
