8. Caracterização de junta soldada por atrito linear com mistura (FSW) da liga Al-Mg-Si AA 6063. / Friction stir welded joint characterization of 6063 aluminum alloy.
Friction Stir Welding process arose from a desire to apply the principles and benefits of traditional solid state friction welding friction in non axi-symmetric geometries. Thus, it was added a traveling speed and a special rotating tool that allows welding aluminum alloys with bad weldability. The key factor to have a linear friction welding with sound bead
