容器焊缝角变形度检测

Measuring of angular deformation degree of container welding seam

根据断裂力学的基本理论，提出了用标准圆弧法和三点检测法对容器焊缝角变形度进行检测的方法．实践证明，对受检圆弧为单个凹凸的情形，这种检测方法具有检测精度好，使用方便的特点．

According to the basic theory of fracture mechanics, the method using a standard circle-arc method and three-point method to measuring the angular deformation degree of a container welding seam is proposed in this paper. Experiment shows when the circle-arc being measured has single bump and hole point, this method is convenient and has a better accuracy.
