This review paper focus on Parametric optimization in Metal inert gas welding by using MOORAS method. MIG is arc
welding process. Parameters optimization can be done by Multi-objective optimization on basis of ratio analysis and analytical
Heriachy process. Ranking of alternatives determine by attributes weight or related importance given between attributes and on
the values of the selected attributes,MOORA method is very fast and robust. It needs minimum Mathematical calculations and
calculations time. Review paper endeavor process to illustrate problem by MOORAS method.
