Tungsten Inert Gas (TIG) welding is one of the extensively used joining process of aluminium alloy. This process is popular because it gives good weld bead and less metallurgical changes in the outside of HAZ to achieve the good mechanical properties in comparison to other arc welding process. The weld joint accuracy and quality mainly depended on the process parameter like welding speed, current, voltage, gas flow rate etc. This paper focused on process parameter of TIG welding i.e. (travel speed, and current) and other parameters have been kept constant throughout the study and enhancement of mechanical properties of weld joint and optimization of the process parameter. The present work describes the effect of a process parameter of TIG welding in respect of mechanical properties i.e. Ultimate tensile strength of weld joint and hardness of weld bead of AA5052 H32 aluminium alloy, for joining of aluminium plate, filler material AA4043 (Al-5Si (wt. %)) have been used.
