The Effect of Traveling and Rotation Speeds on Mechanical Properties during Friction Stir Welding of Dissimilar Al Alloys

Interest in Al alloys for ship construction has increased because of the advantages of high speed with lightweight, increased load capacity, and ease of recycling compared to fiber-reinforced plastic. This study determined that the optimum traveling and rotation speeds for friction stir welding of 5052-O and 6061-T6 Al alloys for shipbuilding applications are 61 mm/min and 1600 RPM, respectively.
