Claim 0:
1. A butt-welding device (10) for butt welding workpieces (3, 4), comprising:
first (1) and second (2) clamping members for receiving ends (13, 14) of the workpieces (3, 4) that are to be joined, wherein at least one clamping member (1, 2) is configured to be moved between an initial position and a welding position;
at least one deburring tool (5, 6) for deburring the workpiece ends (13, 14) after the workpiece ends are welded;
at least one sensor (7, 8) configured to determine a geometric dimension of the workpieces (3, 4) selected from the group consisting of: diameter, width, height, and a combination thereof, in the joining plane or in a plane substantially parallel to the joining plane, wherein the at least one sensor (7, 8) is arranged above the clamping members (1, 2) on a mount for the clamping members (1, 2); and
a control unit (19) configured to control movement of the clamping members (1, 2) and/or movement of the deburring tool (5, 6) as a function of the geometric dimension(s) of the workpieces (3, 4) in the joining plane or in a plane substantially parallel to the joining plane so that deburring is performed from a side of the one of the workpieces (3, 4) determined to have a larger geometric dimension than the other one of the workpieces (3, 4).
