Effect of Welding Parameters on AA8090 Al-Li Alloy FSW T-Joints

Abstract:

In aeronautics and aerospace construction, whenever a seam is needed between aluminum alloy parts, riveting, nailing or bolting are the preferred methods of junction. Friction stir welding technology has made possible the realization of high strength aluminum alloy joints, which are normally considered non-weldable with conventional welding techniques.
