摘要： The present invention relates to a method of welding a wear layer onto a parent material (8), wherein a welding current is applied in each case to a first wire electrode (5) and at least one second wire electrode (5a), which are continuously fed to the parent material (8) for producing a common weld pool, wherein metal powder (7) is fed to the weld pool, wherein welding powder (6) is fed to the weld pool, wherein the wire electrodes are flux-cored wire electrodes (5, 5a), having a core (10) and a covered electrode (11), wherein the flux-cored wire electrode (5, 5a) has a higher alloy than the weld deposit analysis of the wear layer (9) to be welded on, wherein the covered electrode (11) of the flux-cored wire electrode (5, 5a) consists of an alloy which has magnetization properties suitable for the adhesion of the metal powder (7).
