Abstract:
Welding control method and control apparatus, by means of which the welding current is controlled during welding such that the temperature of the weld joint and/or component to be welded remains as close as possible to the same temperature. The welding current is reduced evenly and linearly or the welding current is controlled continuously according to any variable function or curve. The welding current can also be controlled gradually or in appropriate steps in the desired direction.
