Notes:
The influence of roll angle of the FSW tool rotation axis on tensile properties of joints wasexamined to clarify the allowance of deviation from proper tool posture for three-dimensionalfriction stir welding. A5083-O plates of 3 mm in thickness were butt welded by three-dimensionalcontrolled FSW machine. Transversal inclination of the tool (roll angle of the tool) was continuouslychanged from 0 degrees to 10 degrees for both sides. Butt joints ruptured at base metal within therange of roll angle of the tool plus/minus 2 degrees, and ruptured at the thin part made by inclinedtool shoulder entering in the range by plus/minus 7 degrees. Over the range of plus/minus 7 degrees,butt joints ruptured at elongated cavities made by tool inclination at the border of stir zone and basematerial
