摘要
介绍了利用超声相控阵检测钢制对接焊接接头的技术,该检测技术可使缺陷的检出与定量更为精确、有效。在检测结果的自动记录图上,除A型显示外,还有B型、C型及S型显示,并提供了缺陷的三向视图。
Phase - array ultrasonic imaging technique used in the detection of butt weld joints was introduced in this paper. This detection technique can make the checkout and quantum of defects more precise and effective. On the auto - recording chart of measuring results, besides exhibition of A pattern, B pattern and C pattern as well as S pattern were also displayed. Three - dimensional view of defects was supplied.
