Beschreibung
Zusammenfassung:	A friction stir welding method utilizes a joining tool comprising a friction surface; a first workpiece comprising a first treating layer, a second workpiece comprising a second treating layer, and a joining member with a melting point lower than that of the first workpiece and the second workpiece. The joining member is arranged at the joining portion of the first workpiece and the second workpiece, and abutting the first workpiece and the second workpiece. The friction surface of the joining tool is positioned to resist at least one of the first treating layer and the second treating layer. The joining tool is rotated and moved to agitate at least one of the first workpiece and the second workpiece, until at least part of the first workpiece and the second workpiece are plasticized and joined together.
