Abstract
Plasma-MIG welding in which a thermally ionizable inert gas stream is flowed through a nozzle non-consumable electrode having a central aperture and a surrounding annular aperture toward a workpiece and is thereby split into a central gas column enveloped by an annular gas shield. A consumable electrode is fed through the central gas column toward the workpiece, with the establishment of a MIG-arc therebetween. A plasma arc is spontaneously established by means of the MIG-arc between the nozzle non-consumable electrode and the workpiece.
