A joining method head is proposed for fixation to a movable frame, in particular to a robot, having a holding means for an element to be joined to a part, a joining drive means to move the holding means along a joining direction for joining, and a feeding means for feeding elements to the joining method head. Here a control means to control the joining drive means is arranged at the joining method head spatially distanced from the holding means and the joining drive means, so that the holding means and the joining drive means form a joining tool of small dimensions, and means are provided to pass on the elements fed to a transfer station of the feeding means in each instance to the holding means from in front.

1. A method of joining elements to workpieces, the method comprising: (a) automatically and individually transferring the elements from a stationary feeder unit to a transfer station in a first discrete movement step;(b) moving the transfer station on a robotic member;(c) rotating a welding head to the transfer station prior to automatically and individually transferring the elements from the transfer station to the welding head in a second discrete movement step;(d) moving the welding head relative to the transfer station; and(e) performing step (a) while the welding head is joining an already fed one of the elements. 2. The method of claim 1, wherein the rotating step (c) includes rotating the welding head relative to the robotic member such that an element holder of the welding head grabs the next of the elements to be welded when the holder is rotated away from a welding location. 3. The method of claim 1, further comprising: (a) converging at least one of the elements into a receptacle of the transfer station through a conduit;(b) rotating the receptacle and the element about an axis oriented substantially transverse to an elongated axis of the conduit after step (a); and(c) pushing the element into a holder for temporary retention while the receptacle is rotated back to a position aligned with the conduit. 4. The method of claim 1, further comprising linearly advancing the at least one of the elements in the welding head with an electromagnetic actuator. 5. The method of claim 1, further comprising arc welding the elements to the workpieces. 6. The method of claim 1, wherein each of the elements includes an elongated shank and an enlarged head. 7. The method of claim 1, further comprising moving the elements between the feeder unit and the transfer station with compressed air. 8. The method of claim 1, further comprising temporarily interrupting movement of the elements at the transfer station with means for holding each of the elements. 9. The method of claim 1, further comprising moving an electrical control unit with the robotic member, the control unit controlling operation of the welding head. 10. A method of transferring fasteners, the method comprising: (a) moving elongated members of an articulated robot;(b) individually moving the fasteners from a bulk location to an intermediate location;(c) moving the intermediate location with at least one of the members;(d) interrupting movement of the fasteners at the intermediate location;(e) rotating a head attached to the robot to move one of the fasteners from the intermediate location to a third location associated with the head attached to the robot while remaining ones of the fasteners are retained at the intermediate location;(f) automatically moving the third location relative to the intermediate location and the bulk location; and(g) rotating the head holding one of the fasteners while at least another of the members extends through a workpiece opening. 11. The method of claim 10, further comprising rotating the head relative to the intermediate location such that a fastener holder of the head grabs the next of the fasteners when the head is rotated toward the intermediate location and away from a workpiece location. 12. The method of claim 10, further comprising: (a) moving at least one of the fasteners into a receptacle of the intermediate location through a conduit;(b) rotating the receptacle and the fastener about an axis oriented substantially transverse to an elongated axis of the conduit after step (a); and(c) pushing the fastener into a holder for temporary retention while the receptacle is rotated back to a position aligned with the conduit. 13. The method of claim 10, further comprising linearly advancing at least one of the fasteners in the head with an electromagnetic actuator. 14. The method of claim 10, further comprising: moving at least one of the fasteners from the bulk location to the intermediate location substantially simultaneously with moving another of the fasteners from the intermediate location to the third location; andarc welding the fasteners to workpieces. 15. The method of claim 10, wherein each of the fasteners includes an elongated shank and an enlarged head. 16. The method of claim 10, wherein the fasteners are rivets. 17. The method of claim 10, further comprising: (a) pneumatically moving the fasteners between the bulk location and the intermediate location; and(b) mechanically moving the fasteners between the intermediate location and the third location. 18. The method of claim 10, further comprising maintaining the bulk location substantially stationary while moving the head which is a welding head rotated by a remotely located driver. 19. The method of claim 10, further comprising moving an electrical control unit with at least one of the members, and controlling fastening movement of the device with the electronic control unit. 20. A method of manufacturing, the method comprising: (a) pneumatically transferring a first weld stud from a stationary bulk feeder to a transfer station;(b) moving the transfer station on a robotic member;(c) interrupting movement of the first weld stud at the transfer station;(d) rotating a welding head relative to the transfer station and then removing the first weld stud from the transfer station with a holder of the welding head;(e) transferring a second weld stud from the feeder to the transfer station substantially simultaneously with at least step (d);(f) generating a welding arc from the first weld stud after the welding head rotates the first weld stud away from the transfer station; and(g) controlling the welding head with a controller that moves with the robotic member but is spatially separate from the welding head which rotates mechanically independently from the controller. 21. The method of claim 20, further comprising: (a) moving at least one of the weld studs into a receptacle of the transfer station through a conduit;(b) rotating the receptacle and the weld stud about an axis oriented substantially transverse to an elongated axis of the conduit after step (a); and(c) pushing the weld stud into a holder for temporary retention while the receptacle is rotated back to a position aligned with the conduit. 22. The method of claim 20, further comprising linearly advancing the first weld stud with an electromagnetic driver. 23. The method of claim 20, further comprising moving an electrical control unit with the robotic member, the control unit controlling operation of the welding head. 24.
