A process for the electric arc welding of cast iron, specifically white cast iron, is provided which comprises electrically applying to the cast iron to be welded, at welding temperatures, a welding material obtained by melting a welding rod containing, by weight, from about 2.30 to about 3.00 percent carbon, from about 0.03 to about 0.06 percent chromium, from about 0.01 to about 0.04 percent nickel, about 0.01 percent molybdenum, from about 0.82 to about 0.90 percent manganese, from about 0.023 to about 0.032 percent sulphur, from about 0.103 to about 0.115 percent phosphorus, about 2.64 percent silicon, with the balance being iron plus incidental impurities, with the welding rod having a low hydrogen flux.
