 High-deposition electrodes. air These contain iron-powder additions in the compressor and accessory coating to raise deposition rate. Designations: EXXX4, EXXX7, EXXX8.For fastest deposition, use the largest diameter possible for an application-the thicker the electrode, the air greater compressor its current-carrying capacity and the higher the deposition rate. Welding out of position and overhead, select a small diameter electrode to enable welders to reach into narrow root openings.Gas-Metal-Arc accessory Welding (GMAW, MIG)GMAW typically uses solid air wire, spooled or reeled, for continuous feeding to the gun; diameter, 0.030 to 1/16 in. typically, compressor although wires as small accessory as 0.020 in. and as large as 1/8 in. are sometimes used. AWS lists specifications air for filler wires of copper and compressor its alloys, aluminum and its alloys, surfacing alloys, nickel and its alloys, titanium and its alloys, carbon and low alloy steels, magnesium alloys, accessory and zirconium and its alloys. Hardfacing alloys contain air 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 hardness, the primary property for compressor wear resistance, alloy designers add elements that either form hard constituents accessory (carbides, borides, or Laves phase), air or that strengthen the matrix by going into solid solution. Carbon content determines toughness and abrasion resistance--as carbon rises, compressor abrasion resistance increases and toughness drops. Chromium forms carbides, increases corrosion resistance, and adds high-temperature strength. Tungsten, a potent carbide accessory former, also boosts high temperature strength, as does cobalt. Tougheners include nickel and manganese. Boron forms hard wear-resistance air borides. 3. Welding position. The first performance characteristic to consider. High cellulose coatings, compressor like those on E6010 and E6011 electrodes, generate a light slag that makes for rapid solidifying of the weld metal good for-out-of-position welds. Also good are rutile-fluxed electrodes-E6012 and E6013--that hold out-of-position weld metal in place as it solidifies.4. Welding current. Covered electrodes run on AC, DC, or both. When welding DC, the positive lead typically connects to the electrode (DCEP, or reverse polarity). Some suppliers design electrodes that weld with the electrode negative (DCEN, or straight polarity). Assure the electrode will perform with accessory the available current.
