Influence of Flat Friction Stir Spot Welding Process Parameters on Quality Characteristics of AA6082Weld


In this article Flat FSSW of three sheets of AA6082 was carried out having thickness of 1mm for each plate. The tool with probe and tool without probe were used for welding process. The use of these tools helps in obtaining the sound quality weld free from keyholes and cracks. The process parameters considered are tool rotational speed of 400, 975 and 1550 rpm, dwell time of 4, 6 and 8 s and plunge depth of 2.6, 2.8 and 3.0 mm. Taguchi analysis was used to optimize the parameters of this investigation for obtaining high tensile strength. An orthogonal array, L9 was applied and analysis of variance (ANOVA) was done to explore the importance of process parameters on various response.
