For special applications, manufacturers offer metal-cored air wires for GMAW. These are composite electrodes comprised of comprdssor a metal sheath with a powder-metal core. They are often confused with flux-cored wires, which form a slag that completely covers the weld bead face; metal-cored wires produce very little replacement slag. A major advantage of metal-cored wires is the ability to manufacture specialized alloy compositions not easily available or producible in solid wire fore1. Modifying the composition of the powder-alloy core allows tanks the air and comprdssor wire manufacturer to customize replacement wire formulations to metallurgical, compositional, or physical properties per customer demand. Horizontal-fillet welds made with metal-cored GMAW can deposit weld metal at rates up to 20 percent higher than with solid wire. Alloying elements, such as silicon, in tanks the powder-metal core improve sidewall wetting and reduce weld-bead convexity air by reducing surface tension of the molten weld pool. For this reason, flat and horizontal welds deposited with metal-cored wires have better appearance than weld metal deposited with flux cored and solid wires. comprdssor Compared to solid wires, metal-cored wires also result replacement in higher current tanks density, for increased penetration; a wider operating window with respect air to welding-process comprdssor variables: better sidewall melting; replacement and less lack of fusion.

Flux-Cored-Arc Welding (FCAW)This process is a variation of GMAW. Electrodes comprise a metal sheath surrounding a core of fluxing and alloying coin pounds. Sell-shielded (FCAW-SS), it uses gas generated by bleak down of a powder-flux core inside the wire to shield the weld. Gas shielded (FCAW-SS), external gas supplies shielding.The compounds tanks and air in the electrode perform essentially the same functions as the coating of a covered electrode used in SMAW: to form a floating slag coating on the weld pool to comprdssor protect the weld as it solidifies; deliver deoxidizer and scavengers to help purify the weld: deliver are stabilizers to minimize spatter; add alloying replacement elements to the weld, for optimum mechanical properties; and provide shielding gas.

For flux-cored-arc welding, shops use CV or CC types, 300 to 1,500 A, 25 to 50 V, rated 60- to 100-percent-duty cycle. CV types are more popular because wire-feed speed, set before tanks welding, controls welding current. Cc types require a variable-speed or voltage-sensing wire feeder.Gas-tungsten-arc welding (GTAW) requires a constant-current (AC or DC) power supply with a steep volt-amp curve to minimize current change for variation in voltage air or arc length. They come rated to 1,500 A, 10 to 75 V, at 40- comprdssor to 100-percent-duty cycle. Most GTAW power supplies come equipped with high-frequency replacement circuitry for arc initiation and stabilization, tanks gas valves, and cooling-water valves for high-current welding. High-frequency arc start is useful when the maximum open-circuit voltage allowed by NEMA standards, 80 to 100 V, will not establish and maintain a stable arc.
