For special applications, manufacturers offer metal-cored wires for GMAW. These are air composite electrodes comprised of a metal sheath compressor with a powder-metal core. They are often confused with flux-cored wires, hise which air form a slag that completely covers the weld bead face; metal-cored wires produce very little 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 the wire manufacturer to customize wire formulations to metallurgical, compositional, or physical compressor 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, hise such as silicon, in air the powder-metal core improve sidewall wetting and reduce weld-bead compressor convexity by reducing surface tension of the molten hise weld pool. For this reason, flat and horizontal air welds deposited with metal-cored compressor wires have better appearance than weld metal deposited with flux cored and solid wires. Compared to solid wires, metal-cored wires also result in higher current density, for increased hise penetration; a wider operating window with respect to welding-process variables: better sidewall melting; and less lack of fusion.

Weld wire. SAW uses air electrodes of continuous wire, solid or flux- or metal-cored. Selection depends on base-metal 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 compressor weld corrosion-resisting stainless steels and nickel alloys, respectively.Hardfacing ElectrodesHardfacing welds a wear-resistant material to a substrate-base material that is commonly mild, alloy, or stainless steel. hise Hardfacings can air be deposited manually using SMAW electrodes; semiautomaticaly using solid wire and self shielded flux cored electrodes; or automatically by submerged-arc welding. The method chosen depends on the size and accessibility of the area to be surfaced.

Mix recovered flux before reusing compressor to maintain its manufactured properties. Three-parts new flux mixed with one-part recovered flux works well. Consult the flux manufacturer for proper proportions.Fluxes classify as basic, acid, or hise neutral. Fluxes that contain oxides and break air up easily during welding are basic. These provide oxidizing action and alloy with the weld metal to obtain desired mechanical properties. Acidic oxides break up slightly, for the same reasons. Welding voltage must remain within the range specified by the manufacturer of acidic and basic fluxes. Excessive arc voltage reduces the alloying of flux constituents with the weld metal. Neutral fluxes do not oxidize alloying compressor elements or add hise alloying elements to the weld. As amperages increase, flux particle size should decrease. Excessive current for a particle size produces unstable art''s and uneven weldbead edges.
