Abstract
The current study aims to examine how different parameters in friction stir spot welding influence hardness and tensile strength, while identifying the most suitable parameter combinations to enhance the overall quality of the fabricated components. The experimental work involves joining dissimilar materials, where one specimen consists of Aluminum alloy 6061 reinforced with 10% fly ash, and the other is a copper alloy. Various process conditions are altered during testing to evaluate their impact on the mechanical behavior of the welded joints. The process parameters varied and their respective values are speed of the tool 1120 rpm, 1400 rpm and 1800 rpm & Dwell Time on – 20 sec, 23 sec, and 26 sec. here the process is done using tool pin depth as 2.5mm and 2.8mm. The parameter optimization was carried out through the Taguchi approach by adopting an L18 orthogonal array. Minitab software was utilized to perform the analysis and determine the most effective combination of process settings. The better work piece is investigated by using SEM analysis to verify the metallographic structures.
