1. A welding process for welding aluminum, comprising:

  • measuring a force between two welding electrodes on aluminum elements to be welded with at least one force sensor and transmitting the measured force value to a welding control;

    until a set welding time elapses, calculating and storing with the welding control during and/or after elapse of predeterminable incremental time frames at least one of at least one absolute value and at least one increase in the measured force;

    comparing with the welding control the at least one of the at least one absolute value and the at least one increase in the measured force in each case with at least one of a reference value and a reference curve;

    calculating a control deviation resulting from the comparison; and

    after the elapse of the set welding time, subjecting the welding electrodes to a current of a constant level during a welding time extension that follows the set welding time, the current of the constant level being dependent on a magnitude of the control deviation that is calculated at a point in time of the elapse and/or during the set welding time.
