摘要
通过对某装置氧气球罐焊缝中埋藏缺陷的返修,借助相控阵检测技术对缺陷进行定量复查,为缺陷返修提供了详细的技术数据,保证了缺陷挖补工作的顺利完成。通过对挖补过程中缺陷的现场解剖,进一步验证了相控阵检测技术由于具有检测灵敏度高、检测结果直观、可实时显示、缺陷定量准确的技术特点,在球罐等大型压力容器检测等领域应用前景广阔。
The advantage of the PA technology was analyzed. With the aid of PA technology, it provides accurate defect position,length and height and ensure the smooth completion of the repair work. The patc- hing process defect anatomic site, further validation of the phased high detection sensitivity, detection result is intuitive, real - time technical features, such as in spherical tank of large pressure vessel cation prospects. array inspection technique using their display, defect quantitatively accurate detection and other fields broad appli-
