Short-circuiting arc welding process

摘要

The method of controlling the welding operation in short-circuiting arc welding with regularly alternating arc-burning phase and short-circuiting phase, with which not only is the formation of spatter eliminated to the greatest possible extent and a sound weld obtained and the noise during welding reduced but the energy consumption is also significantly reduced, is constituted in such a way that the actual welding current and the actual welding voltage are continuously detected and the instantaneous welding power is calculated. The welding current and/or the welding voltage is then reduced in a controlled manner to such an extent that the instantaneous welding power does not exceed a predetermined maximum value.
