Abstract: A build-up welding method is disclosed in which a welding torch is guided along a metallic workpiece and at least one melting wire serving as a build-up material is fed at an infeed speed into the arc between at least one non-melting electrode of the welding torch and the workpiece. In order to achieve a build-up welding method with higher build-up speeds in comparison to the prior art, it is proposed for the non-melting electrode positioned normal to the workpiece to be guided along the workpiece and for the fed wire to also be moved back and forth along its infeed direction.

Abstract: A build-up welding method (100) is disclosed in which a welding torch (1) is guided along a metallic workpiece (2) and at least one melting wire (5) serving as a build-up material (6) is fed at an infeed speed (9) into the arc (4) between at least one non-melting electrode (3) of the welding torch (1) and the workpiece (2). In order to achieve a build-up welding method (100) with higher build-up speeds in comparison to the prior art, it is proposed for the non-melting electrode (3) positioned normal to the workpiece (2) to be guided along the workpiece (2) and for the fed wire (5) to also be moved back and forth along its infeed direction (9).

Abstract: A device for feeding a welding wire to a welding device is disclosed, having a carriage guide, having a carriage that is supported on a carriage guide so that it is able to move along a carriage axis, particularly in a linear fashion, having an advancing drive, which has an advancing device that is provided on the carriage and driven to induce an advancing motion of the welding wire, and having a carriage drive, which includes a drive unit, an eccentric that is driven by the drive unit, and an eccentric rod that is eccentrically mounted on the eccentric and is mechanically coupled to the carriage to induce a reciprocating motion to the carriage, said carriage drive having means for adjusting the stroke of the reciprocating motion of the carriage.
