Abstract
An electric arc welding method is provided, wherein an electrode assembly comprises at least two fusible continuous electrodes acting on a workpiece for generating a weld pool via electric arcs, wherein the at least two electrodes are arranged in sequential order relative to a welding direction and laterally separated relative to each other, wherein steps are performed of monitoring at least one stability parameter (Stab_par) for each electrode of the electrode assembly; determining if one electrode of the electrode assembly violates a stability criterion (Crit); separating at least temporarily the one electrode violating the stability criterion (Crit) from one or more adjacent electrodes when a violation of the stability criterion (Crit) of the one electrode is detected.
