Beschreibung
Zusammenfassung:	A friction welding process includes: providing a first workpiece having a first weld surface, and a second workpiece having a second weld surface; aligning the workpieces with the weld surfaces facing each other, moving one workpiece relative to the other workpiece, and engaging the first and second weld surfaces such that the movement raises the temperature at the weld surfaces to create a weld interface; and ceasing the movement and allowing the weld interface to cool to weld the workpieces together at the interface. The first workpiece has a plurality of flash removal channels formed in and/or adjacent to the first weld surface. The channels provide pathways for ejection of material from the weld interface during welding.
