US Patent 11819958 Build-up welding method

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.
