摘　　要：应用计算机 CAD 技术的人机对话功能,依据钢结构设计参数,结合焊缝实际结构和尺寸,绘制斜探头超声波焊缝截面扫查过程的动态图形,同时,模拟斜探头超声波探伤过程。实践证明,该技术能形象准确、定量地反映真伪缺陷回波位置,提高超声波钢结构焊缝探伤的准确性。 The dynamic drawing of exploring the welded seams with diagonal ultrasonic flaw detectors is obtained by the CAD according to the design parameter in steel structure with the actual structure and size of the welded seams. At the same time the process of the ultrasonic detection by using diagonal flaw detectors can be simulated. It is proven that the technology can make the image accurate reflect the position of true/false defect quantitatively and increase the accuracy of the detection in the welded seams of the steel structure by using the ultrasonic method.
