以钢板中规则缺陷以及平板对接焊缝缺陷为研究对象,按照JB/T4730.3-2005标准,利用横波探头对钢板中规则缺陷以及焊缝中已知缺陷用不同的测长方法测长,通过一系列的试验工作获取钢板及平板对接焊缝中缺陷长度的超声检测数据,并与缺陷的实际尺寸进行比较,为实际工作中选取恰当的缺陷测长方法提供有价值的参考。
Taking the regular defects in steel plates and the flaws in butt welds of flat plate as the research objects, according to the standard of JB / T4730.3-2005, using the transverse wave probe to measure the regular defects in the steel plate and the known defects in the weld by different length measuring methods, A series of experiments have been conducted to obtain the ultrasonic testing data of the defect length in the butt weld of steel plate and flat plate and to compare with the actual size of the defect so as to provide a valuable reference for selecting the proper method for measuring the length of defects in practical work.
