In order to provide an improved method for producing metal structures which allows a high level of flexibility in respect of process speed of production, material composition of the metal structure, production accuracy, and the quality of the produced metal structure, according to the invention, a second metal additive is supplied to a welding point on a metal base material, which second metal additive is fused at least by a second electric arc produced between a second electrode and the metal base material in order to produce a second weld seam at the welding point, wherein different materials are used as the first metal additive and as the second metal additive, and wherein the first metal additive and the second metal additive are supplied to the welding point sequentially in time and are fused in the region of the welding point in whichever of the first and second electric arcs is burning, in order to form the three-dimensional metal structure.
