摘要:
超声波探伤计算建筑钢结构熔透对接焊缝的缺陷率, 对含有不同位置缺陷及缺陷率的焊缝进行拉力
试验, 用缺陷率-焊缝强度关系图分析焊缝抗拉承载力达到:母材强度, GB50017-2003 一、二、三级熔透对接焊
缝设计值, 母材屈服强度标准值时, 建筑钢结构熔透对接焊缝可允许存在的体积性缺陷率限值.研究结果表
明:存在于熔透对接焊缝中部的缺陷, 当缺陷率小于2.6%时, 焊缝的抗拉强度大于母材的强度, 当缺陷率小
于8.0%时, 焊缝的抗拉强度大于母材屈服强度标准值, 当缺陷率小于25.5%时, 焊缝的抗拉强度大于
GB50017-2003 一、二级熔透对接焊缝设计值, 当缺陷率小于30.0 %时, 焊缝的抗拉强度大于GB50017-2003
三级熔透对接焊缝设计值;存在于熔透对接焊缝根部的缺陷, 当缺陷率小于11 .0%时, 焊缝的抗拉强度大于
母材屈服强度标准值以及GB50017-2003 一、二级熔透对接焊缝设计值, 当缺陷率小于23 .0 %时, 焊缝的抗拉
强度大于GB50017-2003 三级熔透对接焊缝设计值.
