| 摘 要： | 基于超声TOFD技术检测缺陷位置和尺寸的原理,应用多通道超声TOFD检测系统检测了110 mm厚的2.25Cr1Mo钢试块中的横孔和切槽,给出了试块的D扫描和A扫描图像,分析了两者的对应关系.试验结果表明,缺陷位置和尺寸的误差＜5%,验证了超声TOFD方法在缺陷定位和定量上具有较高的准确性.为应用超声TOFD设备进行现场检测时获得的自然缺陷图像的评定提供了有效的依据. |

| Abstract: | Based on the principle of ultrasonic TOFD technique for the detection,location and sizing of defects,the side drilled holes and notches in a 2.25Cr1Mo steel block of 110 mm in thickness were inspected using a multi-channel TOFD inspection system.The D scan and A scan images of defects were given.The corresponding relationship between D scan and A scan image was also analyzed.The errors of defects location and size were no more than 5%.The result validated the good measurement accuracy of ultrasonic TOFD testing.Thus,criterion was provided efficiently for evaluation of natural defect images examined by ultrasonic TOFD equipment on site. |
| Keywords: | Ultrasonic TOFD testing Side drilled hole Notch Location Sizing |
