<p>The invention relates to a method for positioning a welding bolt ( 15 ), held in a bolt welding head ( 3 ), whereby the robot ( 5 ), to which the bolt welding head ( 3 ) is fixed, moves the bolt welding head sideways until a touch sensor ( 21 ) contacts a side wall ( 25 ) of a workpiece. The position of the side wall ( 25 ) is thus detected and the bolt welding head ( 3 ) can be moved through a set amount (Y) into a welding start position, from whence the welding bolt ( 15 ) can be welded to the workpiece ( 9 ) by the displacement in the direction of travel (V). The welding bolt ( 15 ), thus, always has the required separation (Z) from the side wall ( 25 ), independent of tolerances in the workpiece.</p> |
