Arc welding involves in a localized heat application in the substrate plates. The uneven heat distribution causes defects which influence the desired properties of welded joint. This project is studied about the welding distortion residual stress and the temperature distribution in the butt joint of thin plates welding. Double ellipsoid heat source is generated and finite element analysis were carried out using finite element code - ANSYS software. Experimental analysis was carried out by varying thickness of plates and the input parameters like voltage and current. The effect of distortion, residual stress for the varying parameter was observed. Thermocouples were placed in different nodes of the plates for observing the temperature distribution in the respective measuring nodes. LAB VIEW software was used to display the thermal curves by using the collected signals from the thermocouples.
