Abstract
In this experiment, TIG welding parameters influence on weld-ability of both stainless steel 304 and mild steel 1018 specimens with a dimension of 150 mm long x 75 mm wide x 3 mm thick is investigated. This paper investigated the microstructure and mechanical properties of dissimilar materials such as SS and MS joints by tungsten inert gas (TIG) welding. Fusion welding techniques are extensivelyadopted for joining ferrous and non-ferrous alloys.Performance of Tungsten inert gas (TIG) welding on between stainless steel 304 and Mild steel 1018 plate has been studied by optical microscope. The work objectives were the joining of dissimilar steel alloys was done by TIG welding with the innumerableinput variable like voltage, welding speed, and gas flow rate.
