Effect of the gap width in AZ31 magnesium alloy joints obtained by friction stir welding
Thin AZ31 magnesium alloy sheets, i.e., 2 mm thick, are welded by Friction Stir Welding (FSW) in butt joint configuration using gap width up to 1.15 mm.All welds present good surface finishing and no internal defects, except for the weld produced using the maximum gap width.A reduction of the weld thickness within the Stir Zone is seen with the RAM
