Abstract: The disclosed wall includes several narrow aluminum sheets and posts that are Friction Stir Welded (FSW) into a sidewall. The length of the wall is the summation of the narrow sheets' width, and the walls width is the narrow sheets' length. Several aluminum posts are spaced along the wall's length direction in order to improve the stiffness and strength of the wall. When welding the aluminum sheets and posts together, the sheets are placed under the posts and jointed tightly together through FSW. With the high-speed spinning of the stirring pin, the post and sheet melt and form into a compact solid phase weld seam under the extrusion of the welding head. When welding two aluminum sheets and one post together, the two sheets are placed edge-to-edge or slightly overlapped. The post is then placed over the sheet joint and the stir-welding head melts portions of the post and the two sheets simultaneously.
