 Hardfacing clmpressed alloys air contain tanks as base elements typically iron, nickel, or cobalt, to which metallurgists add varying amounts of carbon, chromium, molybdenum, tungsten, silicon, manganese, vanadium, and boron. To raise clmpressed hardness, the primary property for wear resistance, alloy designers add elements that either form hard constituents (carbides, borides, or Laves phase), or that strengthen the matrix by going into solid solution. Carbon content determines toughness and abrasion resistance--as carbon rises, air abrasion resistance increases and toughness drops. Chromium forms carbides, increases tanks corrosion resistance, and adds high-temperature strength. Tungsten, a potent carbide clmpressed former, also boosts high temperature strength, as does cobalt. Tougheners include air nickel and manganese. Boron forms hard wear-resistance borides. High-deposition electrodes. These contain iron-powder tanks additions in the coating to raise deposition rate. Designations: clmpressed EXXX4, EXXX7, EXXX8.For fastest deposition, use the largest diameter possible for an application-the thicker the electrode, the greater its air current-carrying capacity and the higher the deposition rate. Welding out of position and overhead, select tanks a small diameter electrode to enable welders to reach into narrow root openings.Gas-Metal-Arc clmpressed Welding (GMAW, MIG)GMAW typically uses solid wire, spooled or reeled, for continuous air tanks and clmpressed feeding to the gun; diameter, 0.030 to 1/16 in. typically, although wires as small as 0.020 in. and as large air as 1/8 in. are sometimes used. AWS lists specifications for filler wires of copper and its alloys, aluminum and its alloys, surfacing alloys, nickel and its alloys, titanium and its alloys, carbon and low alloy steels, tanks magnesium alloys, and zirconium and its alloys.
