Friction Stir Welding (FSW) is carried out on armour grade AA5083 aluminium alloy having the dimensions of 100X75X6.35 mm. The FSW process and tool parameters play a major role in deciding the joint strength. Many processing conditions and material properties affect the microstructure evolution and mechanical behaviours of the produced joints. Various parameters such as welding speed, tilt angle, spindle speed and various tool profile are used. Analyzing the mechanical behaviours of joints welded like tensile strength and hardness were investigated. The tool rotation and welding direction same side are similar is called Advancing side (AS) and opposite on the other known as retreating side (RS). The input process parameters which influence the strength of the joints. Main consideration is to select the best parameter to produce the defect free joints. Experiment is designed to determine the major factors affecting the hardness and tensile strength of the joints. Effect of rotational speed, welding speed and tilt angle on tensile strength and hardness are studied. The contribution of each factor is determined from ANOVA analysis “Tensile strength and hardness increased with increasing the rotational speed 1000 rpm to 1400 rpm, traverse speed from 30 mm/min to 40mm/min”. This investigation mainly deals with Taguchi and ANOVA were performed to improve the effective characteristics of welding inputs.
