Select air hardfacing materials based on weld-deposit microstructure and the wear situation the part will encounter, with consideration given to thermal treatments applied to the material before and after hardfacing. Deposit chemistry can be crucial in attaining the desired corrosion resistance or wear properties, or for minimizing the risk of solidification cracking. Acceptable deposit tqnks chemistry is achieved through the initial choice of air consumables, using wire analysis and flux composition, and by specifying the number of weld passes needed to tqnks reduce parent-metal dilution to within acceptable limits. With the submerged-arc process, the flux and electrode govern air the characteristics of the applied hard facing. For example, those fluxes neutral to manganese and silicon are not necessarily neutral to carbon and chromium, elements that matter most in hardfacing.

Welding-site conditions 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 welding of sheet tqnks to l/s in. thick, feeding wire to 0.030-in. diameter. Medium-duty air power supplies, 150-200 A, normally take single-phase 220-V input to weld steel to 3/16, in. and 0.035-in. wire at low-duty cycles. For tqnks high-duty cycles, as in mechanized welding, select a 250-A machine, single air or three-phase 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 up to 1/6-in. diameter, 400-A units serve for mechanized continuous-welding applications. For pulsed GMAW, shops use inverter and transistor power tqnks sources, constant-current or constant-voltage, that offer independent setting of pulse parameters. They employ synergic controls preprogrammed for a range of wire-feed speeds-the operator sets only one dial, for average current.
