A friction-weldable stud (22) is provided. The stud includes an elongate body (32) having a collar or skirt (38) located around the body and extending outwardly therefrom. The collar (38) has a first surface (40) facing in one direction toward one end of the body, with the surface having an engagable configuration for engagement by a cooperating configuration of a chuck of a welding tool. The tool can thereby rotate the stud (22) and also apply an axial force to it through the chuck and collar (38). The collar (38) has a second surface facing away from the first surface preferably with an annular groove (48) which helps shape the weld material and control flash during the welding. The body also has a friction-weldable nose or end extending outwardly from the collar (38) in the direction of the axis of the elongate body (32) by means of which the stud (22) can be affixed to a workpiece by a friction-welding technique. |
