焊瘤缺陷对钢管直接相贯节点极限承载力的影响研究

Research the Influence of Welded Tumour Defects on the Ultimate strength of Directed Welded Tubular Jionts

采用ANSYS程序定量分析绘制了背景工程中检测到的焊瘤缺陷对钢管直接相贯节点的极限承载力影响曲线,根据影响曲线得出较大的焊瘤缺陷应引起重视并给予磨除清理的结论和建议。

It is generally acknowledged welded tumour defect is no influence on the ultimate strength of structure bearing quiet load.This article with ANSYS program quantificationally analyzes and drawes the influence curves of welded tumour defecte on the ultimate strength of directed welded tubular jionts that have been inspected in background project, and according to the influence curves drawes the following conclusion and propose: the great weldrd tumour defect should cause attention and be rubbed off and cleared up.
