超声波探伤中的缺陷精确定位问题是超声波探伤的主要任务之一。文章介绍利用超声波数据采集系统采集的数据 ,实现对缺陷的大小及位置的精确定量。缺陷的大小由缺陷数据与标准缺陷波数据的比较得出 ;缺陷的精确定位通过计算超声波在工件中的传播时间求得
The precise localization of defects in ultrasonic flaw detection is one of the main tasks of ultrasonic flaw detection. The article introduces the use of ultrasonic data acquisition system to collect data to achieve the exact size of the defect and the location of quantitative. The size of the defect is determined by comparing the defect data with the standard defect wave data; the exact location of the defect is calculated by calculating the propagation time of the ultrasonic wave in the workpiece
