A Review on the Parametric Optimization in MIG Welding using Taguchi Method

In the contemporary, MIG welding has wide industrial applications. Parameters utilized in MIG plays a significant role in overall quality, productivity, duration as well as cost of welding. This paper throws light on the influence of welding parameters like welding current, welding voltage, gas flow rate, wire feed rate etc. on the weld strength of Medium Carbon Steel material during welding. By the use of DOE method, the parameters can be optimized to ascertain the best possible combination to achieve desirable quality. Taguchi technique has been used to plan the set of experiments and acquiring the data. An orthogonal array, Signal to Noise Ratio (S/N) and ANOVA is utilized to investigate the welding characteristics of Steel and thereby attaining the welding parameters which gives out desirable result. The confirmation test compares the predicted values with the experimental values to confirm the effectiveness in the analysis of weld strength.
