Abstract: A method for gas metal arc welding, as well as to a device for gas metal arc welding and the use of an additional gas during gas metal arc welding, wherein a wire electrode is melted by an arc, wherein the arc burns between the wire electrode and a work piece, and an inert gas is supplied, and wherein an additional gas in the form of at least one additional gas flow directed toward the tip of the wire electrode is supplied in addition to the inert gas.

Abstract: In order to additionally develop a forming device for delivering at least one root shielding gas to the root side of at least one region to be joined of at least one object, as well as a corresponding method, such that discolorations and the formation of coatings on the object to be joined are effectively prevented, the invention proposes that the delivered root shielding gas is directed, and guided or deflected in the direction along the root side of the region to be joined.
