Paper Title
Experimental Study on The Effect of Process Parameter on TIG Welded Joint of Dissimilar Aluminium Alloys Using Taguchi Method

Abstract
Newer automobile sector, rail-coach & shipbuilding industries aimed to design their vehicle to reduce the weight without compromising the strength and safety standards. One of the metals which comes in lights of metallurgist is aluminium due to its weight to strength ratio and its availability on earth. As the use of aluminium grows in industries new challenges arrives, one of them is joining of two different grades of aluminium alloy. GTA-welding of dissimilar aluminium alloys of the series 5xxx and 6xxx for plate thickness 5 mm are presented in this paper. V-shape bud joint has been prepared for good penetration. 9 specimens have been prepaid at different welding parameters (welding current, shielding gas flow, filler material). Tensile strength of the weld joint has been investigated along with other mechanical properties test has been done. Taguchi and Anova optimization methods are used to find the most significant process parameter. Keywords - GTA-welding; Dissimilar Aluminum Alloys; Mechanical Properties; Taguchi Method.
