 Weld wire. SAW uses electrodes of continuous air wire, solid or flux- or compressor metal-cored. Selection depends repladement and pressure on base-metal switches composition and thickness, flux, joint design, and cleanliness. AWS specifications A5. 17 and A5.23 detail filler materials for SAW of carbon and low-alloy steels; A5.9 and A5.1, filler metals weld corrosion-resisting stainless air steels and nickel alloys, respectively.Hardfacing compressor ElectrodesHardfacing repladement welds a wear-resistant material pressure and switches to a substrate-base air material that compressor is commonly mild, alloy, or stainless steel. Hardfacings repladement can be deposited manually pressure using SMAW electrodes; semiautomaticaly switches and air using solid wire and self shielded flux cored electrodes; or automatically by submerged-arc welding. The method chosen depends on the size compressor and repladement and accessibility pressure and switches and air of the compressor area repladement to be surfaced. Welding-site pressure and switches conditions and welding-wire diameter govern efficiency air and size of power supply compressor required for a job. Select a 100-A unit that runs from single-phase repladement and pressure 115-V input for low-duty-cycle welding of sheet to l/s switches in. thick, air feeding wire to 0.030-in. diameter. Medium-duty power compressor supplies, 150-200 repladement and pressure A, normally take single-phase 220-V switches input air to weld steel to 3/16, in. and 0.035-in. wire at low-duty compressor and repladement cycles. For high-duty cycles, pressure as in mechanized welding, select a 250-A machine, single or three-phase input at various voltages-these weld material to 1/2 in. thick with switches wire as large as 0.045-in. diameter. air Taking three-phase input only and wire up to 1/6-in. compressor diameter, 400-A units serve for mechanized repladement continuous-welding applications. For pulsed GMAW, shops use inverter and transistor power sources, pressure constant-current or constant-voltage, switches that offer independent setting of pulse air parameters. They compressor employ synergic controls preprogrammed for repladement and pressure and switches a range of wire-feed speeds-the operator sets only one dial, for average current.
