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.

Methods, devices, and systems for providing certification of friction stir welds are disclosed. A sensor is used to collect information related to a friction stir weld. Data from the sensor is compared to threshold values provided by an extrinsic standard setting organizations using a certification engine. The certification engine subsequently produces a report on the certification status of the weld.
