To keep the filling ratio of welds constant in arc welding, in particular of such welds with a varying size of cross-section of the weld groove, the distance of the welding gun from the workpiece is kept constant, the welding current intensity and/or the welding voltage is measured, and the measured value of the welding current intensity or the welding voltage is compared with a predetermined desired value corresponding to the desired filling ratio. If the measured value deviates from the predetermined desired value, the welding speed and/or the welding power is correspondingly changed.
