The aim of this research work is to obtain optimum process parameters for dissimilar metals (AISI 304Stainless Steel and CP- Copper) welding using Gas Tungsten Arc Welding (GTAW) process. Study the mechanical andmetallurgical properties of weld joint and optimizing process parameters so as to achieve optimum weld strength andmicrohardness. The experimental setup consists of semi-automatic welding machine with control over weldingparameters such as root gap, joint angle, welding current. The DOE (Design of Experiment) method applied for theexperiments is Response Surface method (RSM) with Central Composite Design (CCD). The DOE will be prepared usingMINITAB software. The experimental readings will be then taken like ultimate tensile strength and microhardness of theweld joint. Moreover microstructure will be performed to examine microscopic description of the individual constituentof material, and macrostructure inspection will be performed to examine of weld quality. Optimization of processparameters will be been carried out using the Response Surface Methodology (RSM). This will be done using the softcomputing tool MINITAB.
