针对在用压力容器钢板双边区域的长条状分层缺陷,采用相控阵0°垂直线性扫描方式,对相控阵图像进行分析,从而正确识别和判定双边区域的长条状分层缺陷。
Aiming at the long stratified defects in the bilateral region of the pressure vessel plate, the phased array 0 ° vertical linear scanning mode is adopted to analyze the phased array images so as to correctly identify and determine the long stratified defects in the bilateral regions.
