A study of friction stir welding of 0.2 in. thick plates of Ti-6A1-4V has shown that the technology is feasible for joining such alloys, report researchers at the Edison Welding Institute, Columbus, Ohio; and the Air Force Research Laboratory, Materials and Manufacturing Directorate, Wright-Patterson Air Force Base, Ohio.

The specific goals of the study were to produce defect-free welds; document tool load, torque, and temperature; determine rates of tool wear; characterize weld microstructure; understand microstructure evolution; and measure tensile properties of the welds. ...
