ABSTRACT:
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.
