Process for judging the quality of a welding joint between two sheet metal parts during resistance welding comprises reducing the distance between the welding electrodes (4a, 4b) in a closing phase of the welding tongs so that the current actual value (33) on the current actual value output (21) of the power part (15) reaches a current limiting value predetermined by a tongs control (24) and/or the drive speed exceeds a predetermined speed limiting value. An Independent claim is also included for a welding device for carrying out the process, comprising electrodes (4a, 4b), an electrically driven spindle (7) for moving the electrodes, units for producing a welding current, a tongs control (24), a position regulator (25) for the electrical drive (6), units for acquiring the spindle position, and a power part (15).
