In this paper, the authors describe a method which allows for an as low an energy input as possible in the short-circuit phase of a gas-shielded metal arc welding.
Abstract: 
The invention relates to a method used in gas-shielded metal arc welding during the striking phase of welding. The aim of the invention is to provide a method which allows for an as low an energy input as possible in the short circuit phase. To this end, the method is characterized in that when the short circuit phase begins a control is activated and remains active for the duration of the short circuit. When a characteristic threshold value S1 is fallen short of, the control increases the energy input (phase A), and stops the energy input when a threshold value S2 is reached and then reduces the energy input (phase B).
