Apparatus and Method for Regulating the Position of a Tong-Shaped Tool

A welding facility, comprising:

• a welding tool including a welding tong having two electrodes configured to produce a welded connection on at least one component;
• a drive device configured to drive the welding tool in order to apply a force which the two electrodes exert on the at least one component when producing the welded connection;
• at least one force sensor attached to a stationary arm of the welding tool and/or to a movable arm of the welding tool, wherein the movable arm is movable relative to the stationary arm;
• and
• an apparatus for position regulation of the welding tool, the apparatus including (i) a determination module configured to determine a normalized displacement signal, in which a deflection of the welding tong due to an effect of a mechanical force generated on the welding tong during a work process using the welding tool is compensated for, and (ii) a force regulation module configured to regulate a progression of the force which the welding tong exerts on the at least one component during the work process based on the normalized displacement signal.
