NUMERICAL SIMULATION OF WELDING DISTORTION IN THIN PLATES

A three-dimensional model based on the finite element method is developed to simulate the temperature field and stress distribution in the welding and heat affected zones during fusion welding of thin plates. The governing equations are solved using the SYSWELD program commercial code. The model’s predictions are tested and verified against the experiments. Angular distortion and longitudinal bending are measured, the results are compared with those obtained from the mathematical model, and a relatively good agreement between them is found. The verified model is used to evaluate the effects of various parameters on the temperature and stress distributions in the welding and heat affected zones of a thin austenitic stainless steel plate.
