| Abstract: | In order to predict welding distortion of 7A52 aluminum groove structure, MSC.MARC software of finite element was adopted to simulate MIG welding process of this structure, and comparison was made with the practical welding distortion data. The results indicate that the numerical simulation can predict the distortion trend of aluminum structure, and the predicted data approach the practical measured one. |
