Abstract

Abstract: Gas Tungsten Arc Welding (GTAW) is most commonly used for welding Aluminium Alloys in most of the industrial applications. The base metals used in this research work is Al 7075 in plate form. In this research investigation, current (A), welding speed (mm/min) and flow rate (lt/min) are the input parameters and tensile strength (MPA) is the output parameter to check welding strength. Generally, this type of welding depends largely on the current and welding speed. This research work extended to identify the effect of process parameters in various mathematical calculations. Optimization part has been performed using Full Factorial Design (FFD) which is used to check the quality of welding parameters. The Statistical software has been used to identify the quality of process parameters.
