为了研究多参数对T型焊接接头残余应力的影响，运用ANSYS有限元分析软件对手工电弧焊T型焊接接头进行焊接数值模拟，分析不同参数变化对于接头残余应力的影响规律。研究结果表明：焊接结构的残余拉应力随焊缝长度的增加而增加，随腹板厚度、底板厚度的增加而减小；焊接速度对于焊接结构残余应力也有较大影响，在靠近焊缝中心位置，焊接速度越快产生的残余拉应力峰值越小。

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.
