| 摘要 |
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 he ad (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 displacement in the direction of trave l (V). The welding bolt (15), thus, always has the required separation (Z) fro m the side wall (25), independent of tolerances in the workpiece.
