摘要
针对单收发探伤方式 ,应用几何光学的理论 ,近似地计算了一倍近场长度以外受管子表面曲率影响的管道对接焊缝中长横孔和球孔的距离 波幅曲线 。
Based on the theory of geometric optics, the amplitude distance curves of the long transverse and spherical holes in small diameter tube seams by single probe mode were calculated and verified, considering the influence of the curvature of the tube with the distance beyond the nearfield.
