OK 73.05 SMAW Type Basic E7018-G Description Welds in offshore flowlines welded with standard 1% Ni consumables have demonstrated corrosion resistance that is considerably lower than that of the base material. OK 73.05 has been alloyed with Cr/Cu to provide increased corrosion resistance at the level of the base material. It is a basic electrode with very good welding characteristics, specially designed for pipe welding.
