MIG welding is one of the most widely used welding techniques due to its versatility and ease that can be maintained in almost all kind of working conditions. 304 Stainless Steel possessing high strength and toughness is usually known to create major challenges during its welding. The MIG welding operation of SS304 (S30400) to find out the response variables as they are able to respond fast with changing input variables and these input variables or parameters should be flexible to adopt new technological changes. A framework has been developed to study performance measurement based on previous researches on “Design of Experiment (DOE) approach and Taguchi Method”. In this study four input or control parameters namely current, voltage, wire speed and gas flow rate which are responsible (significant) for major changes in two response variables namely hardness and deposition rate has been used. This study analyzes the future effects of variation to the input parameters. The results prove that during the welding of 304 Stainless Steel, voltage and Current are the most significant factors for the effect on hardness and wire speed and current are most significant factors that are affecting deposition rate.
