The invention relates to a welding electrode for electric arc welding intended for joint welding and built-up welding stainless steels, particularly steels with a ferrite-martensitic, ferrite-martensite-austenitic or martensite-austenitic structure, and is characterized in that the electrode in the shape of a bare wire or a wire with a coating deposits a weld metal whose alloying constituents affecting the structure lie within the following analysis limits: 0.01-0.05 percent carbon, 0.1-0.9 percent silicon, 0.5-4.5 percent manganese, 15.0-18.0 percent chromium, 4.5-7.5 percent nickel, 0.2-2.5 percent molybdenum, 0.02-0.12 percent nitrogen and 0.2-3.5 percent tungsten, the remainder iron apart from the unavoidable impurities. The alloying constituents shall be adapted manually in such a way that the following two equations with the chromium equivalent (Cre) and the nickel equivalent (Nie) are satisfied:
