Friction-stir-welded butt joints of AA6111-T4 sheets were made at ultra-high joining speeds of up to 6 m/min in an effort to further lower the cost and push for the application of FSW in industrial settings. The ultra-high speeds lead to a drastic change in thermal and mechanical history during the formation of the welds. Mechanical tests on the joints prove that the higher welding speeds result in virtually no change or slightly improved mechanical performance compared to the parent materials. Microstructural characterization using EBSD found that as welding speed increases the local micro-texture changes both in type and distribution.
