Method for producing a welding wire, welding wire for processing a component, and component

Abstract

The invention relates to a method for producing a welding wire that includes the steps of providing a hollow wire, through at least part of which at least one cavity extends; producing the welding wire by introducing a welding material containing titanium aluminide or at least one nickel-based superalloy into the at least one cavity, the at least one cavity being evacuated or being filled with a protective gas before, during and/or after the introduction of the welding material, and the hollow wire being formed from nickel if the welding material contains the at least one nickel-based superalloy. Further aspects of the invention relate to a welding wire and to a component having at least one component region obtained by hardfacing using at least one such welding wire.
