This paper presents the simulation of Metal-Inert-Gas (MIG) arc welded part distortion and its correlation with test for an automotive engine cradle. A Finite Element Analysis (FEA)-based method is developed to predict the welding distortion. The developed technique has elastic- plastic constitutive material model with temperature-dependent material properties. The inherent shrinkage of weld and two weld sequences are simulated. In addition to distortion, residual stress and plastic strain distributions are obtained from the analysis. The heat sink effect is also analyzed using transient thermal-mechanical analysis. The predicted welding distortion is in reasonable accuracy as it correlated with test data.
