本文分析了曲率半径为61～81mm的环焊缝中的缺陷投影与缺陷位置的几何关系,并根据此关系绘制缺陷定位曲线,介绍了其使用方法及在实际生产中的应用情况。
In this paper, the geometrical relationship between the defect projection and defect location in the circumferential weld with the radius of curvature of 61 ~ 81mm is analyzed. The defect location curve is drawn according to the relationship, and its application method and its application in practice are introduced.
