<p>A method for welding with at least two sealing off electrodes (4,4') to which two different potentials are applied, where a common welding bath (7) of a leading electrode (4) and a trailing electrode (4') is formed. The leading electrode (4) has a larger electrode diameter compared with the trailing electrode (4').. An independent claim is given for an inert gas mixture for tandem welding with two electrodes.</p> |
