This paper using the FEM software Marc, for the 50 and 60 degree V groove of flat plate butt joint simulate the one-layer and three layers welding, finish each welding and cooling it down to room-temperature then start the next welding true represent process and get the temperature field, residual deformation and welding residual stress, according to the theory analysis and empirical equation verified the temperature field and residual deformation all correct, comparison with experiment verified the welding residual stress regularity and correctly.

本文利用有限元软件Marc，对开60°和50°V型坡口的平板对接接头，动态的模拟了单层单道打底焊，焊完一道后让试件冷却到室温以及单层单道满焊，每焊完一道后让试件冷却，然后再焊下一焊道，道间温度≤200℃，在以此为初始边界条件下开始下一道的焊接，真实的再现了焊接过程，得出了温度场，残余变形和残余应力场的分布规律，根据理论分析及经验公式验证了温度场以及残余变形的正确性，角变形的大小，这些结果与数值计算相吻合。通过与实验测得的残余应力进行比较，验证了焊接残余应力的分布规律及模拟的正确性。
