Effect of Friction Welding Conditions on Mechanical Properties of AA6082-AA2024 Joint

Abstract

The work highlights weld quality as a gauge of weld performance and examines the impact of rotational speed on friction stir-welded (FSWED) AA2024 and AA6082 alloys using square tool. Utilizing Square stir tool of shoulder and pin diameters of 20 mm and 7 mm, respectively, both alloys (6 mm thick) were joint. Using varying rotational speeds—1000, 1400, and 2000 rpm—specimens were welded at a specified tool traverse speed of 25 mm/min. Both Flexural Strength and tensile strength were strongly impacted by variations in parameters. Maximum Tensile and Flexural strengths obtained at 1000 RPM and 20mm.min i.e. 143.43 MPa and 282.17 MPa respectively.
