Abstract
A friction stir method includes providing a joining tool, a mold comprising a top surface and a cutout defined from the top surface, and a workpiece comprising a treatable layer and arranged on the top surface of the mold. The joining tool resists the workpiece, and rotates and moves to agitate the treatable layer of the workpiece along an extending direction of the cutout of the mold, until a protrusion integrated with the workpiece is formed in the cutout of the mold.
