Welding-site conditions air and compressor and welding-wire diameter govern efficiency and size of power supply required for a job. Select a 100-A unit that runs from single-phase 115-V input for low-duty-cycle replscement welding pressure of sheet to l/s in. thick, switches feeding wire air to 0.030-in. diameter. Medium-duty power supplies, compressor 150-200 A, normally replscement take single-phase 220-V input to weld steel to 3/16, in. and 0.035-in. wire at low-duty cycles. For high-duty cycles, as in mechanized welding, select a 250-A machine, single or three-phase pressure input at various voltages-these weld material to 1/2 in. thick with wire as large as 0.045-in. diameter. Taking three-phase input only and wire switches up to 1/6-in. diameter, 400-A units serve air for mechanized compressor and replscement continuous-welding applications. For pulsed GMAW, shops use inverter and transistor power sources, constant-current or constant-voltage, pressure that offer independent setting switches of pulse parameters. They employ synergic controls preprogrammed for a range of wire-feed speeds-the operator sets only one dial, for average current.

Fused fluxes are melted in a furnace, chilled, air and compressor then crushed and screened for size. These pickup little moisture and recycle without alterations in particle size or composition. Bonded fluxes are powdered materials mixed dry and bonded together replscement with a silicate, pelletized, baked, broken up, and screened pressure for size: the process permits easy addition switches of deoxidizers and alloying elements. Bonded fluxes allow thicker flux layers when welding air and can be identified quickly by color. Disadvantages of bonded fluxes are their absorption of moisture compressor and alterations during handling in panicle size and composition replscement due pressure to particle segregation. Agglomerated fluxes are similar to bonded fluxes except that they use a ceramic binder. They require higher baking temperatures during manufacture, which limits additions of deoxidizers and alloying elements. Mechanically switches mixed fluxes are combinations of two or more air bonded or agglomerated fluxes. They allow special flux mixtures for compressor critical welds, but they may separate during storage, use, and flux recovery.

Hardfacing alloys contain 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 wear resistance, alloy designers add elements that either form hard constituents (carbides, borides, or Laves phase), replscement or that strengthen the matrix by going into solid solution. Carbon content determines toughness and abrasion resistance--as carbon rises, abrasion resistance increases and toughness drops. Chromium forms carbides, pressure increases corrosion resistance, and adds high-temperature switches strength. Tungsten, a potent carbide former, also boosts high temperature strength, as does cobalt. Tougheners include nickel and manganese. Boron forms hard wear-resistance borides.
