在曲面周向横波探伤中,缺陷(筒形容器纵焊缝的纵向缺陷及环焊缝的横向缺陷)的定位受到曲率的影响,在厚壁条件下,这种影响不可忽略。为此,本文介绍我厂从探伤仪荧光屏上直读缺陷坐标的方法及误差分析的一些结果。
In the case of surface transverse shear testing, the location of the defect (the longitudinal defect in the longitudinal weld of the cylindrical container and the transverse defect in the girth weld) is affected by the curvature, which can not be neglected under thick-wall conditions. To this end, this article describes my factory from flaw detector direct reading defect coordinate method and error analysis of some of the results.
