Abstract：

Two main methods, inactive element method and quiet element method, to simulate the process of multilayer and multipass welding were reviewed, and the shortcomings of both methods were discussed as well. Based on these analyses, a method called node dynamic relaxation method was put into forward to simulate the multilayer and multipass welding process, and the principle and application of this method were discussed in detail. The simulating results show that using the node dynamic relaxation method can decrease mesh distortion, improve calculation efficiency, and obtain good simulation results. This method can also be used in the field of simulation addition or removing materials in finite element analysis.

Key words： inactive element method quiet element method node dynamic relaxation method multilayer and multipass welding finite element analysis (FEA)
