Stud joining apparatus

摘要

A welding apparatus for joining a weldable fastening element onto a workpiece by a welding process, wherein the welding apparatus comprises: an electric welding power source; a fastening element holding device for holding the fastening element during welding; a first drive device for moving the fastening element holding device along a first axis; a cleaning electrode holding device for holding a cleaning electrode along a second axis; and wherein the cleaning electrode is connectable to the electric welding power source. The fastening element holding device and the cleaning electrode holding device are mounted on a common tool carrier and the tool carrier is movable on a joining head by a tool carrier drive from a joining position to a cleaning position, and in the joining position the first axis defines a joining axis, and in the cleaning position the second axis is aligned with the joining axis.
