摘要： A resistance welding apparatus includes a welding controller configured to control a welding tool. The welding controller has an assignment device including a parametrization device. The assignment device is configured to read out a current point to be welded from a list of points to be welded, to read out a first setpoint curve from a record of a database assigned to the current point to be welded, and to assign the first setpoint curve to the first regulator and the parametrization device is configured to read out the first value from the record of the point to be currently welded and to parametrize a first parameter of the first regulator with the first value. The welding controller further includes the first regulator configured, using a first parameter, to regulate a temporal profile of an electric current at the current point to be welded in accordance with the first setpoint curve.

摘要： A welding process for the welding of aluminium includes a force sensor measuring a force between two welding electrodes on aluminum elements to be welded and transmitting its measured values to a welding control. Until the elapse of a set welding time, the welding control calculates and stores at least one absolute value and/or at least one increase in the measured force. The welding control compares the measured absolute value and/or the increase in the measured force with a reference value and/or a reference curve and calculates a control deviation from the comparison. After the elapse of the set welding time, the welding control subjects the welding electrodes to a constant current during a welding time extension that follows the set welding time, dependent on a magnitude of the control deviation that is measured at the point in time of the elapse and/or during the set welding time.

摘要： A control apparatus for a welding tool includes a determination module for determining a normalized displacement signal, in which a deflection of a tong-shaped tool, due to an effect of a mechanical force generated on the tool during a work process using the tong-shaped tool, is compensated for. The control apparatus further includes a force regulation module for regulating a progression of the force which the tong-shaped tool applies to at least one component during the work process on at least one component. The force regulation module is configured to regulate the progression of the force during the work process based on the normalized displacement signal.
