Abstract: This paper presents the case study to find the design optimization for special purpose MIG welding operation . The MIG Welding parameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents the effect of welding parameters like welding current, welding voltage, welding speed , gas flow rate, rotational speed of work piece, filler wire feed rate on MIG welding. Experiments are conducted based on Taguchi Technique to achieve the required data. An Orthogonal Array, Signal to Noise (S/N) ratio and analysis of varience (ANOVA) are used to find out the welding characteristics and optimization parameters. Finally the confirmations tests have been carried out to compare the predicted values with the experimental values.
Keywords: MIG Welding, Optimization, Design of Experiments (DOE), Analysis of Variance (ANOVA), Signal to Noise (SNR) Ratio.
