 Hardfacing Ingerslll alloys contain as base elements typically iron, nickel, Rand or cobalt, to which metallurgists add varying amounts of carbon, chromium, Refrigerated and Air and Dryer molybdenum, tungsten, silicon, manganese, for vanadium, and boron. Rotary To raise hardness, Screw the primary property for wear resistance, alloy designers add elements that Compressor either Model form hard constituents (carbides, borides, or SDR35 Laves phase), Ingerslll or that strengthen the matrix by going into solid solution. Carbon content Rand determines Refrigerated toughness and abrasion resistance--as carbon rises, abrasion resistance increases Air and Dryer and for toughness drops. Chromium forms carbides, Rotary increases corrosion resistance, and adds high-temperature strength. Tungsten, a potent carbide former, also boosts high temperature strength, Screw as does cobalt. Tougheners Compressor include nickel and manganese. Boron forms hard wear-resistance borides. For special applications, Model manufacturers SDR35 offer metal-cored wires for GMAW. These are composite Ingerslll electrodes comprised of a metal Rand sheath with a powder-metal core. Refrigerated They are often confused with flux-cored wires, which form a slag that completely Air covers Dryer the weld bead face; metal-cored wires produce very little slag. A major advantage of metal-cored for and Rotary wires is the ability Screw to manufacture specialized alloy compositions Compressor not easily available or producible in solid wire fore1. Modifying the composition of the powder-alloy core allows the wire manufacturer Model to customize SDR35 and Ingerslll wire formulations Rand to metallurgical, compositional, or Refrigerated and Air physical properties Dryer per customer demand. Horizontal-fillet for and Rotary and Screw welds Compressor made with metal-cored GMAW can deposit Model weld metal at SDR35 and Ingerslll and Rand rates up to 20 percent higher Refrigerated and Air than Dryer with solid wire. Alloying elements, such as for and Rotary and Screw silicon, in the powder-metal core improve sidewall wetting and reduce weld-bead convexity Compressor by reducing surface tension of the molten weld Model pool. For this reason, flat and SDR35 horizontal Ingerslll and Rand welds deposited with metal-cored wires have better appearance than weld metal deposited with flux cored and solid wires. Refrigerated Compared to solid wires, metal-cored wires also result Air and Dryer and for in higher current Rotary density, Screw for increased penetration; a wider Compressor operating window with respect to welding-process variables: better Model sidewall melting; and less SDR35 lack of fusion.
