APPLYING ANSYS SOFWARE FOR PREDICTING TEMPERATURE DISTRIBUTION, DEFORMATION AND STRESS IN WELDED BUTT JOINTS
Article presents an application of ANSYS software for predicting temperature distribution, deformation and stress in welded butt joints. Both Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW) are used for butt jointswelded plates and pipes, respectively. Heat source which is very difficult to calculate in fusion welding processes is determined in current work. Hence, the ANSYS is applied to create the model of welded joints and simulate the GMAW and GTAW. Results show the temperature distribution, the deformation and the stress after welding. These results that were obtained from using diffirent welding conditions were compared together to evaluate effect of welding parameters to the temperature, the deformation and the stress. They are important platform for finding an appropriate welding condition decreased welding defects as well as experimental times, leading to reduce the cost of welding.
