Optimization of Welding Parameter (Mig Welding) Using Taguchi Method

Metal Inert Gas welding (MIG) process is an important component in many industrial operations. The GMA weldingparameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents theinfluence of welding parameters like welding current (Amp.), welding voltage (Volt.), &Wire Feed Rate (m/min) on Tensile strength. A plan of experiments based on Taguchi Method has been used to acquire the data. AnOrthogonal array, signal to noise (S/N) ratio and analysis of variance (ANOVA) are employed to investigate the weldingcharacteristics of mild steel& optimize the welding parameters. Finally the conformations tests have been carried outto compare the predicated values with the experimental values confirm its effectiveness in the analysis of Tensile Strength.
