摘要
文章在《金属结构中缺陷可接受性评估方法指南》(BS7910—2005)的基础上,将环向缺陷作为环向裂纹进行处理,通过固定环焊缝缺陷长度,计算不同缺陷深度对剩余强度的影响。本文对于仅给出环焊缝缺陷的环向长度和轴向宽度,没有给出缺陷深度的缺陷分析提供评价思路和方法。
Based on the'defect of the metal structure of acceptability evaluation guide'(BS7910-2005)on the basis of the circumferential defects,as was to crack,through the fixing ring weld defect length,calculated for different defect depth effect on the residual strength.In this paper,for the given only ring weld defect circumferential length and axial width,the evaluation ideas and methods of analysis of defects is not given the depth of defect.
