Abstract
In this paper the structure and mechanical properties of similar AA5083 FSW joints were investigated, as well as the effects of postweld coldrolling of FSW joints. Two joints were formed using different welding parameters, in order to investigate the influence of parameters on joint properties. The welded joints were tested using nondestructive methods (visual and Xray inspection, electrical conductivity variation) and destructive methods (tensile and hardness testing, metallographic analysis of macro and microstructure). The joints were also coldrolled. It was found that the joint welded using parameters Vrot/Vtr = 750/73 rpm/mm can be successfully processed by cold rolling; it also has better mechanical properties than the joint welded using parameters Vrot/Vtr = 750/150 rpm/mm, and had a more uniform hardness distribution. It was concluded that using parameters 750/73 results in a AA5083 weld of satisfactory quality was obtained.
