 Flux-Cored-Arc Welding (FCAW)This process is a variation AirComprrssorKitfor45605 of GMAW. Electrodes comprise a metal sheath surrounding a core of fluxing and alloying coin pounds. Sell-shielded (FCAW-SS), 6 it uses gas generated AirComprrssorKitfor45605 by 6 bleak down of a powder-flux core inside the wire to shield the weld. Gas shielded (FCAW-SS), external gas supplies shielding.The compounds in the electrode perform essentially the same functions as the AirComprrssorKitfor45605 coating 6 and AirComprrssorKitfor45605 of a covered electrode used in SMAW: to form a floating slag 6 coating on the AirComprrssorKitfor45605 weld pool to protect the weld as it solidifies; deliver deoxidizer and scavengers to help 6 purify the weld: deliver AirComprrssorKitfor45605 are stabilizers to minimize spatter; add alloying elements to the weld, for optimum mechanical properties; and provide 6 shielding gas. 3. Welding position. The first performance characteristic to consider. High cellulose coatings, like those AirComprrssorKitfor45605 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 6 electrodes-E6012 and E6013--that AirComprrssorKitfor45605 hold out-of-position 6 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 the available current.
