Abstract
Dissimilar metal joints are of great interest in many industries. This paper deals with the study on dissimilar fillet joints made by tungsten inert gas welding (TIG) with various shielding gas and filler combinations. Design of experiments performed to optimize the right combination of the process. Metallurgical and mechanical characterization on the dissimilar joints made by TIG welding process was carried out and compared with dissimilar joints made by friction welding. Weldment corrosion behavior was studied by using the potentiodynamic instrument. Dissimilar welding is done by TIG welding process using duplex stainless filler wire with argon shielding gas shown an appreciable increase in pull out strength while compared with other combinations. The dissimilar joint made by duplex stainless steel filler (ER2209) exhibits better pitting corrosion resistance than austenitic stainless steel filler (ER309L).
