ABSTRACT:
A friction-stir welding probe tip is disclosed which has right-handed threads on one portion of the probe and left-handed threads on another portion of the probe such that weld material is drawn to the middle of the weld as the friction-stir welding probe is rotated and passed along the joint region of the pieces to be joined. This probe tip is also fitted with a shoulder region for gripping by a rotation means.
