摘　　要：介绍了将焊接有限元方法引入虚拟制造环境的新思路。将焊接过程的有限元分析集成到虚拟制造环境中,支持产品从机械加工到焊接成型全过程的设计,对需要进行焊接加工的产品实现虚拟设计过程,在实际焊接之前,设计焊接路径,规划焊接顺序,有效预测焊接应力场、温度场,焊件的变形情况,完善虚拟制造内涵,并指导实际生产。The finite element method for welding processing phases in introduced to the virtural manufacturing environment in this paper.The method supports the design of total product manufacturing process from machining to welding, realizes the products needed to weld of virtural design,including to design welding paths,to program welding sequence,to forcast effecitively the cases,such as welding stress field ,temperature field ,welding distortion,so to improve the virtural manufacturing ,and to direct the real manufacturing.
