PARAMETRIC OPTIMIZATION OF METAL INERT GAS WELDING BY USING TAGUCHI APPROACH

The present work deals with optimization of welding process variables by using Metal inert gas welding. In this process input variables are voltage (V), current (A) and welding speed(S) with tensile properties, hardness, and penetration as responses of low carbon steel (ASTM A29). The design of experiments based on Taguchi orthogonal array [L9], acquires Analysis of variance (ANOVA) to determine the influence of parameters with the optimal condition.
