摘要
通过建立数学函数及利用MATALB软件建立图表,研究不同探头对自升式平台桩腿半圆板与齿条板焊缝的超声波检测情况,明确不同角度探头的声束扫查覆盖范围,确定扫查截面范围的重合区域。结果表明,半圆板与齿条板焊缝的不同位置需要采用不同角度的探头联合进行扫查,为检测类似形状工件提供了一种可行的方法。
Through mathematical functions establishment and graph drawing by MATALB software, the researcher studies on different probes＂ ultrasonic testing case on jack up platform spud leg semicircular plate and gear rack plate welding seam, clears the acoustic beam coverage of different angle probes and identifies the overlap regions of scanning section. The results show, the different welding seam positions of semicircular plate and gear rack plate need to be scanned by different angle probes jointly, to provide a feasible method for similar shape workpiece detection.
