摘要

基于有限元软件ABAQUS，建立了单丝双面气电立焊焊接温度场和应力场的有限元模型。热源模型选取圆柱体热源与面热源的组合，并采用生死单元技术来进行焊缝的填充加载，采用试验测定的EH40钢高温热物性参数模拟了焊接过程。模拟计算结果表明：焊后试板的横向残余应力在板中间区域为拉应力，在其余区域为压应力；纵向残余应力在焊缝及其附近区域表现为较大的拉应力，而在远离焊缝的位置拉应力迅速衰减并过渡为压应力；通过与试验结果对比，计算得到的热循环曲线及焊缝形状与实际试验吻合度较高，验证了所建立的模型的准确性。该模型可以用于预测气电立焊焊接过程中的温度场、应力场和残余应力分布，为焊接工艺优化和结构设计提供理论依据。

Abstract

This study established a finite element model of the welding temperature field and stress field of single wire double-sided electro-gas welding using the finite element software ABAQUS. A combination of cylindrical heat source and surface heat source was selected for the heat source model

and the element birth-death technique was used for weld filling and loading. The high-temperature thermophysical parameters of EH40 steel measured experimentally were used to simulate the welding process. The simulation results show that the transverse residual stress of the welded plate is tensile stress in the middle area and compressive stress in the remaining areas. The longitudinal residual stress appears as a large tensile stress in the weld and its vicinity

while the tensile stress rapidly attenuates and transitions to compressive stress at locations far away from the weld. Comparison with experimental results reveals a high degree of agreement between the simulated thermal cycle curves and weld shapes and those obtained from actual tests

validating the accuracy of the established model. This model can be used to predict the temperature field

stress field

and residual stress distribution during the electro-gas welding process of single wire double-sided

providing a theoretical basis for welding process optimization and structural design.
