Optimization of Process Parameters in Tig Welding of Dissimilar Metals by Using Activated Flux Powder

S. S. Sathe, M. S. Harne

Abstract: The welding quality is strongly characterized by the weld bead geometry, which plays an important role in determining the mechanical properties of the weld. The aim of the work is welding of dissimilar metals by the use of activated flux. Mild steel & Stainless steel which find extensive application in the field of Civil, Nuclear, Thermal Power plant etc. Taguchi method is used for optimization of process parameters. The weld specimen is subjected to tensile testing to find out qualitative properties of the weld. ANOVA helps to find out percentage contribution of each parameter & its effect verses objective function.
