Study and optimize tensile strength of FSW joints using AA5083 filler by Taguchi & Anova

Abstract

FSW is a cutting-edge technique that eliminates many of the drawbacks of traditional welding procedures, such as the release of hazardous gases and the need for a large amount of energy to complete the process. Experiments are designed using the Taguchi L9 orthogonal array and ANOVA analysis methods. Analyze the gathered data values to see if tool rotation speed of 850 rpm, 1000 rpm, or 1150 rpm, and tool transverse speed of 25, 35, or 45 (in mm/min) have an effect on the tensile strength of weld joint specimens. FSW fabricates aluminium alloys AA5052, AA5083, and AA6063 in this research utilising AA5083 as filler. Nine specimens with different base metal combinations are created during the experiment, using tool rotation speeds of 850 rpm, 1000 rpm, or 1150 rpm and tool transverse speeds of 25, 35, or 45 (in mm/min). The results show that as the TRS is raised, the tensile strength increases. Taguchi's orthogonal system was used to create the Design of Experiment, which allows for better outcomes with the least number of experiments. FSW has application range in the industrial industry, including shipbuilding, aircraft, and automobile production, and is widely employed in the fabrication of aluminium plates and sheets, as well as steel and magnesium.
