T型熔透焊接头残余应变有限元分析

FEM ANALYSIS ON RESIDUAL STRAIN OF T-WELDING JOINTS

厚板在焊接过程中会产生较大的残余应力和变形,通过对不同形式的T型熔透焊接头的残余应变进行有限元计算,分析了焊缝高度、钢板厚度、预热温度对接头残余应变的影响。

Thick plate in the welding process will produce large residual stress and deformation. Through finite element calculation on residual strain of different forms of T-welding joints, the height of welding line, the thickness of the steel plate, the influence on the residual strain of joints of preheat temperature are analysed.
