Abstract:
A friction stir welding (FSW) tool tip is described. The tool tip comprises a pin portion and a body portion that meet to form a shoulder. The tool tip has a graduated change in composition along its length. In some embodiments, the alloy composition near the end of the pin differs from the alloy composition of the body by at least 0.5% by wt of at least one element. A method of manufacturing a FSW tool tip having a gradual compositional change is also described.
