| 20090078689 | Method of Welding a Wear Layer onto a Parent Material Using a Plurality of Flux-Cored Wire Electrodes, Metal Powder and Welding Powder - A method of welding a wear layer onto a parent material, wherein a welding current is applied to a first wire electrode and to at least one second wire electrode. The first wire electrode and at least one second wire electrode are continuously fed to the parent material for producing a common weld pool. Metal powder and welding powder are fed to the weld pool. The wire electrodes are flux-cored wire electrodes, having a core and a covered electrode. The flux-cored wire electrodes have a higher alloy than a weld deposit analysis of the wear layer to be welded on the parent material. The covered electrode of the flux-cored wire electrodes includes an alloy, which has magnetization properties suitable for adhesion of the metal powder. | 03-26-2009 |
