Friction Stir Welding of dissimilar Materials (AA2024 & AA6063) and Investigation of Mechanical Properties

Effect of friction stir welding parameters on the microstructure and mechanical properties of dissimilar AA2024-AA6061 joints

In the present study, to resolve the problems in fusion welding methods as well as to increase the strength, FSW method was used to join aluminum alloy sheets 6061 and 2024. Moreover, optimal parameters for joining of these two alloys were also taken into consideration. Various tool rotation speeds of 565, 950 and 1500 rpm were selected. For each tool rotation speed, two traverse speed variable...

Effect of tool position on microstructural and mechanical properties of friction stir butt welded joint of AA2024–AA7075 dissimilar alloys

In this research, butt joining of Al2024 and Al7075 plates were performed by Friction Stir Welding (FSW) and the effect of tool position on microstructural and mechanical properties in about 1 mm from center line of joint towards the advancing side (AS) and the retreating side (RS) was investigated at three positions of +1, 0, -1 mm. In this regard, the plates of Al2024 and Al7075 were selected...

Longitudinal Residual Stress Analysis in AA2024-T3 Friction Stir Welding

Friction Stir Welding (FSW) is an innovative solid-state joining process, which is gaining a great deal of attention in several applicative sectors. The opportune definition of process parameters, i.e. minimizing residual stresses, is crucial to improve joint reliability in terms of static and dynamic performance. Longitudinal residual stresses, induced by FSW in AA2024-T3 butt joints, have bee...
