Thecurrentparameterwasfoundtohavethehighestcontribution,accounting for 65.66%of the overall performance of theweldments. Confirmatory testingwasconductedinorder toconfirmtheoptimizationstrategy, andthe findingsindicatedthat theGrey-basedTaguchi techniqueisastraightforward yet effective approach for optimizingwelded connections across several performancecriteria.
