Zusammenfassung:	A friction-weldable stud is provided. The stud includes an elongate body having a collar or skirt located around the body and extending outwardly therefrom. The collar has a first surface 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 rotathe stud and also apply an axial force to it through the chuck and collar. The collar has a second surface facing away from the first surface preferably with an annular groove which helps shape the weld material and control flash during the welding. The body also has a frictionweldable nose or end extending outwardly from the collar in the direction of the axis of the elongate body by means of which the stud can be affixed to a workpiece by a frictionwelding technique. The surface of the nose has a plurality of ridges thereon which are designed to help clean the surface of the workpiece as the stud is rotated during the welding operation. The stud can be made in one piece or in two pieces with the body of the stud and the collar being separate. The collar and the body then can be made of different materials.
