Mechanical and Microstructural Characterization of Single and Double Pass Aluminum AA6061 Friction Stir Weld Joints

Mechanical and Microstructural Characterization of Single and Double Pass Aluminum AA6061 Friction Stir Weld Joints

This study focuses on the effect of single pass (SP), double sided pass (DSP) and normal double pass (NDP) method on friction stir welding of aluminum AA6061. Two pieces of AA6061 alloy with thickness of 6 mm were friction stir welded by using conventional milling machine. The rotational speeds th...
