In this paper, experimental investigation is carried out for Gas Metal Arc welding process for optimizing the tensile vigor of Aluminium Alloy7075-T73.This is arduous to weld Aircraft material utilizing Gas Metal Arc welding process. In this paper the L9 orthogonal array is employed to design the experiments. The experimentation was carried out in Ador Welding Ltd. Pune and the tensile vigor was quantified utilizing Macrocosmic Testing Machine (UTM) at the Sharadchandra Pawar College of Engineering, Otur, workshop.
The cull of erroneous parameters for welding may hazardous to the whole process and positions. This paper proposes and demonstrates the Taguchi’s Method for evaluating the performance measures of GMAW process. The input parameters such as current (Amp), Voltage (V0), welding speed (mm/min) and gas flow rate (Lit/min) are considered for study with tensile vigor as replication factor. The result of the paper can be utilized for maximizing the tensile vigor of AA7075-T73.
