STUDY OF EFFECT OF METAL ARC WELDING PARAMETERS ON WELDING QUALITY BY TAGUCHIS?S ORTHOGONAL ARRAY TECHNIQUE
Abstract
Welding is one of the most important operations widely used in fabrication industries for producing fabricated structures of wider range and utilities. Often welded structures process complex geometrical shape with varying capabilities. Stainless steel structures are widely used in chemical industries as well as in making medical and domestic appliances, because of its wide applications and utility, it became inevitable to study depth of penetration, grain microstructure and ultimate tensile strength of weld joint which in turn is influenced by parameters like current, voltage, and Gas flow rate. The life span of the welded structure and its quality is decided by all of the above mentioned parameters. This study proposes to analysis the quality of the weld by parametric optimization through identification of the most significant parameter, which influences depth of penetration, ultimate tensile strength and microstructure of the weld, and also is to determine optimum range for selected controllable parameters mentioned above. The parametric optimization for best response is envisaged by Taguchi?s Orthogonal Array which is being one of the most widely used statistical tools used by researchers. The experimental results showed that, current and voltages are most significant factors for depth of penetration (DOP) and ultimate tensile strength (UTS). The experimental values are verified with the confirmation test
