Abstract

This thesis presents a finite element method in numerical study of two dimensional transient heat conduction to determine the temperature distribution by using MSC Patran software. The execution of the analysis was done by using MSC Patran software where its shows area that have been affected by heat and area that was free from distortions. This method was functional with the usage of temperatures to calculate the heat development and distribution. The analysis implementation was on the stainless steel plate AISI 304L during welding process with using OTC DR 4000 Robot Welding. Three sizes of electrodes with three different voltages were use in this study to analyze their effect to the MIG welding process. The effect of microstructure changes in welded 304L stainless steel induced by the processes of welding was investigated in the experiment using metallography method. The hardness test was carried out for the weld joint at the weld metal area, heat affected area and base metal area to know the properties of stainless steel after welding.
