 High-deposition electrodes. These contain iron-powder additions in the coating to raise deposition rate. Designations: EXXX4, EXXX7, EXXX8.For fastest deposition, use the largest diameter possible for an application-the ApacheBlueVC1 thicker the electrode, the greater its current-carrying 4in.x50ft.AirHose and ApacheBlueVC1 capacity and the higher the deposition rate. Welding out of position and overhead, select a small diameter electrode to enable 4in.x50ft.AirHose welders to reach into narrow root openings.Gas-Metal-Arc Welding (GMAW, MIG)GMAW typically uses solid wire, spooled or reeled, for continuous feeding to the gun; diameter, 0.030 to 1/16 in. typically, although wires as small as 0.020 in. and as large as 1/8 in. are sometimes used. AWS lists specifications for filler wires of copper and its alloys, aluminum and its alloys, surfacing ApacheBlueVC1 alloys, nickel and its alloys, titanium and its alloys, carbon and low alloy steels, magnesium alloys, and zirconium and its alloys. Iron-base alloys, the most widely used hardfacing materials, combine versatility with moderate cost. They achieve wear resistance by forming carbides and martensite, a hard matrix structure that forms on quenching and toughens 4in.x50ft.AirHose with tempering. Pearlitic alloys, usually containing less than 0.30 percent carbon, are comparatively soft and ductile.Nickel-base ApacheBlueVC1 alloys resist corrosion and heat better than iron-base alloys, They come in three types, depending on the hard phase (boride, carbide, or Laves) that forms on cooling, In boride-containing alloys, large amounts of chromium borides provide 4in.x50ft.AirHose wear resistance.Cobalt-base alloys provide more high-temperature corrosion resistance than iron-base and nickel-base grades. Carbides or Laves-phase give wear resistance. Production vs. repair applications In general, production applications require high-duty-cycle power supplies, ApacheBlueVC1 and repair applications can use low-duty-cycle portable units.Lift-arc GTAW Many DC power supplies are equipped with a list-start feature for, a variation of scratch starting, GTAW welding. When the welder touches the tungsten electrode to the workpiece, a small amount of current--15-20 A--flows. When he lifts the electrode from 4in.x50ft.AirHose the ApacheBlueVC1 work, the arc starts softly and the machine switches to the set weld-current value. 4in.x50ft.AirHose This low-current starting minimizes weld contamination caused by touching the tungsten to the workpiece and eliminates the need for high-frequency starting.
