管道焊缝超声多维成像检测技术
Multiple-View Ultrasonic Imaging Technique for Pipe Welds
摘 要
通过超声C扫描和三视投影成像技术对管道焊缝缺陷进行定性定量评估和诊断分析。研究与应用结果表明，采用超声自动扫描多维投影成像方法可以直观地得到焊缝区缺陷的位置、大小、分布和取向等特征信息，使缺陷识别的准确性和检测可靠性明显提高。该项技术已在电力等工业部门管道焊缝的无损检测中得到应用。

Abstract
A new nondestructive testing and evaluation (NDT&E) technique by using multiple-view ultrasonic imaging based on mobile automated scanning system for pipe welds in-service was described. Ultrasonic C-scan and three-dimensional P-scan were established to evaluation and diagnosis of defects in pipe welds. The results presented showed that the characteristics of defect in weld, for examples, location, distribution and orientation and size of defects and so on, were be exhibited well by employing the approach. It offered an effective instrument for improving NDT&E detectable probability and reliability of finding defects. The developed multiple-view ultrasonic imaging technique had been applicated in NDT&E of pipe welds in steam power industry so far.
