The present invention relates to an arc welding electrode for the purpose of depositing an austenitic weld metal containing at least 7% Ni and at least 15% Cr, said electrode having a tubular, metal envelope and a powder filling, which contains metal powder. The envelope and the powder filling contain the same metallic constitutents together with C and Si, and the ratio of the percentage proportions by weight of each metallic constituent in the envelope in relation to the weight of the envelope to the corresponding percentage proportions by weight of the metallic constituents in the metallic powder in relation to the weight of the metal powder including the C and Si is between 0,75 and 1,33, and preferably between 0,9 and 1,1. The electrode produces weld metal of highly uniform quality. |
