Abstract

Tungsten inert gas (TIG) welding in which the arc is formed between a pointed tungsten electrode and the work piece in an inert atmosphere of argon or helium but the activated TIG welding is that in which oxides of fluxes are used on work piece also called A-TIG. Current and voltage can have profound effect on the material in terms of strength and hardness. This research aims at the study of using conventional TIG (tungsten inert gas) and activated TIG welding process to investigate the effect of different levels of factors (current, voltage, gas flow rate, electrode diameter) on the mechanical properties of the mild steel using mixture of MgO and CaO flux. Mild steel specimens were used during the experimentation. The results of conventional TIG have been compared with the activated TIG welding. The method of design expert is used to carry out the experimentation. Moreover it is observed that there is decrease in hardness of weld but the quality of weld is increased as compared to conventional TIG welding.
