多参数对T型焊接接头残余应力的影响研究
Influence of Multiple Parameters on T-joint Welding Residual Stress
摘要
Abstract
In order to study the influence of multiple parameters on T-joint welding residual stress, it used ANSYS finite element software to carry out numerical simulation for T-joint of arc welding, and analyzed the influence rule of different parameter change on welded joints residual stress. The results indicated that the residual stress of weldment will increase with the increase of weld length, when the thickness of web and bottom slab increases, the residual stress of weldment decreases. The welding velocity also has a significant impact on the residual stress of weldment, when the welding velocity increases, the residual stress peak decreases on the location of weld center.关键词
