Abstract
A method for forming a propshaft assembly includes: providing a tube having an annular wall member and an axial end face; providing a yoke having body and a pair of arms that extend from the body, the body defining an annular groove having sidewalls and an end face, the sidewalls being spaced apart to receive the annular wall member; spinning at least one of the tube and the yoke while engaging the axial end face to the end face of the annular groove to plasticize a portion of the yoke and a portion of the tube; and driving the yoke and the tube together to fuse the plasticized portion of the yoke and the plasticized portion of the tube together and thereby form a friction weld; wherein the tube is fused to the yoke over portions of the yoke that correspond to the sidewalls and the end face.
