Analysis on welding residual stress produced by repairing cracks in the joint of longitudinal rib and deck plate

摘要: 钢桥面板纵肋–盖板焊缝处穿透面板的裂缝通常只能采用重焊方法修复，但所引起的高焊接残余应力易导致结构再次开裂而没有达到预期的修复效果. 选取12 mm钢桥面板中纵肋–盖板裂缝为研究对象，采用子结构算法进行重焊后残余应力分布规律及焊接工艺影响研究. 结果表明，相同条件下，钢桥面板有横梁位置处纵肋–盖板裂缝重焊残余拉应力数值和分布范围均明显高于无横梁位置，采用由中间向两端的对称焊能够有效减小残余应力峰值；裂缝重焊修复过程中焊趾处纵向残余应力随焊缝长度、随坡口角度呈幂函数变化关系.Abstract: Crack penetrating through bridge deck in the joint of longitudinal rib and deck plate can only be repaired by re-welding, however, it will be recurred on account of high residual stress deriving from re-weld process. In this paper, the cracks through the bridge steel deck plate at the joint of longitudinal rib and deck plate are selected as research object, then the residual stress is calculated by substructure method and the influences of welding procedure are considered meanwhile. The results show that, in the same conditions, the numeric value and distribution range for RDF cracks are higher than RD cracks and symmetry welding from middle to both ends is useful to decrease the longitudinal tensile stress. The relationship between the longitudinal residual stress and the re-welding length or the groove angle at welding toes is congruous with the power function relation.
