In this article the application possibilities of welding simulation for vice-frame components are discussed. A three dimensional finite element model has been developed to dynamically simulate the welding process. The investigations focus on the simulation of the model construction and the welding effect on distortions and its stress. Comparisons of experimental and numerical results show good agreement and that the simulation method is reasonable. The vice-frame is a casting component that comes from a goods wagon bogie. So the procedure of the vice-frame simulation can be used for more complex structures like the side-wall, front-wall, roof, floor plate, and so on. It can help that optimize the welding process and improve the welding quality.
