In order to maintain the degree of filling of weld seams constant, especially those seams having a changing size of the cross section of the weld groove, in arc welding, the spacing of the welding gun from the workpiece is kept constant, the welding amperage and/or the welding voltage are measured, and the thus-measured value for the welding amperage or the welding voltage, respectively, is compared with a predetermined set value corresponding to the desired degree of filling. In case of a deviation of the measured value from the predetermined set value, the welding speed and/or the welding output are changed correspondingly. |
