    Abstract: A billet includes a solid steel body and an alloy cladding. The cladding may include a square tube in which the body is inserted with an interface at which the cladding becomes bonded to the body when the billet is heated and rolled or otherwise worked into a ferrous product. At least one element composed of a mass of finely divided scavenging aluminum, titanium or magnesium, is placed in the tube adjacent the body and separate from the interface. The elements are advantageously compressed into briquettes which scavenge oxygen from residual air at the interface to prevent oxidation of the cladding at the interface. The tube may be closed to prevent gases outside the billet from penetrating to the interface. Alternatively, reliance may be placed on the briquettes to scavenge oxygen from the residual air and also from atmospheric air and furnace gases before they can penetrate to the interface.

  • Patent number: 7604872
    Abstract: This disclosure provides a joining area and method between copper and stainless steel or titanium, as well as the permanent cathode obtained, where said joining area is made of a first zone of a copper-nickel (Cu—Ni) alloy, an intermediate zone with a mostly nickel alloy or pure nickel and a second zone made of a stainless steel-nickel alloy, which is the result of the participating materials being cast in an arc welding process, for example TIG, MIG or manual arc using electrodes of nickel as welding contributor between said materials and their space arrangement, that is to say, leaving a separation between the materials when performing the welding process, thus ensuring as follows: a) greater tensile strength, b) a substantial improvement of corrosion resistance of the joint welding, and c) improvement of conductibility, which can be improved still further by modifying the straight design of the conducting bar by providing it with the “horn”-type shape.
