摘　　要：针对变厚度曲面复合构件超声检测中,扫描程序难以根据各扫描点所采集的A型波进行缺陷自动识别的特点,从曲面构件的超声检测原理出发,进行了波形分析和推理运算,采用自动波形跟踪技术,提高了超声C扫描的定位精度和检测效率。In Ultrasonic inspection, scanning program is hard to automatically recognize defect by the A - wave of each scanning point because of varied thickness of curved surface. Automatic waveforms track technology was present based on the theory of ultrasonic inspection about curved surface and the way of waveforms analysis and rational algorithm. Results demonstrate the technology can improve location precision and test efficiency in C scan.
