使用通用有限元软件包 ABAQUS 对多丝埋弧焊 (SAW) 工艺进行了建模。本文简要阐述了焊接工艺及其在厚壁管线管制造中的应用。提出了 SAW 工艺相应的 2D 和 3D 有限元 (FE) 模型。进行有限元分析以研究焊接过程中熔合区和热影响区的传热特性。在考虑或不考虑焊接前成形过程引起的残余应力和应变的情况下，对工艺参数和焊件几何形状的影响进行了评估。在适当的地方给出了有限元预测与实验结果的比较。结果表明，通过工艺优化可以最大限度地减少焊接引起的几何变形以及残余应力和应变。因此，事实证明，有限元分析可以用于更好地理解 SAW 工艺，从而成为未来工艺开发和控制的有用工具，以优化产品性能。
A multi-wire submerged arc welding (SAW) process has been modelled using a general purpose finite element package ABAQUS. The paper explains briefly the welding process and its application in thick wall linepipe manufacturing. Corresponding 2D and 3D finite element (FE) models of the SAW process are presented. FE analyses were carried out to investigate the heat transfer characteristics in the fusion and heat affected zones during welding. The effect of process parameters and weldment geometry have been evaluated with and without the consideration of residual stresses and strains induced from the forming processes prior to welding. Comparisons of FE predictions with experimental results are presented where it is appropriate. It is shown that the geometrical distortion and residual stresses and strains caused by welding can be minimised through process optimisation. It is therefore demonstrated that finite element analysis can be applied to better understand the SAW process and hence be a useful tool for future process development and control with the view of optimising product properties.
