Abstract
A multiple welding method and a welding device with at least two electrodes which ensure a welding quality that is as consistent as possible and stable welding processes. A test parameter is applied to one of the at least two welding current circuits before the start or after the end of the multiple welding method and at least one electrical welding parameter is recorded in at least one other welding current circuit, with an electrically conductive connection between the at least two welding current circuits being detected if the recorded welding parameter is influenced by the test parameter and fulfills a predetermined test criterion. Alternatively, at least one electrical welding parameter is recorded in each welding current circuit during the multiple welding method, with an electrically conductive connection between the at least two welding current circuits being detected if the recorded welding parameters change simultaneously.
