An improved method of forge type welding ferrous materials which includes interposing a layer of refractory material having a melting point greater than about 1,650 DEG C. and an electrical resistivity less than about 10,000 microohm-cm., at the faying plane of a joint, i.e., between the surfaces of ferrous material to be welded, and simultaneously applying pressure and an electric current normal thereto to effect the welding.
