 Electrodes come 3 to 24 in. long, 0.01 to 0.25-in. diameter. Colored markings--bands or dots--indicate composition: pure tungsten, green; CooemanPowermatePortable5 1-percent thoriated, yellow; 2 percent GallonAirTank thoriated. red; ceriated, orange; lanthanted, black.Filler metal GIAW does not usually requite addition of fillet metal, but filler is commonly added when base-metal thickness is greater ModelC5 than 1/8 in. Finer metal for low-carbon (to 0.15 C) CooemanPowermatePortable5 and mild GallonAirTank (0.15 m 0.29 C) steels are described in AWS A5.2; for carbon steel in A5.18; ModelC5 and for low-alloy CooemanPowermatePortable5 and GallonAirTank and ModelC5 steels in A5.28 Flux. AWS specifications A5.17 and A5.23 describe fluxes for saw. AWS designation of fluxes CooemanPowermatePortable5 precedes that of the wire when identifying a combination for a welding procedure. For example, the designation F7A2-EM12K indicates a flux (F) that will provide, with a given wire designation, tensile strength GallonAirTank of 70,000 Psi (7), in the as-welded condition (A), and impact properties of 20 ft lb at -20 F (2). A designation containing a ModelC5 P rather indicates the flux properties after postweld heat treatment. Flux-Cored-Arc Welding (FCAW)This process is a variation of GMAW. Electrodes CooemanPowermatePortable5 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), GallonAirTank external gas supplies shielding.The compounds 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 protect the weld as it solidifies; deliver deoxidizer and scavengers ModelC5 to help purify the weld: deliver are stabilizers to minimize spatter; add alloying elements to the weld, for optimum CooemanPowermatePortable5 mechanical properties; and provide shielding gas. Shielded-Metal-Arc Welding (SMAW, STICK)AWS (American Welding Society) A5 specifications Set standards for electronics for SMAW of carbon, stainless, and low alloy steels; aluminum copper, and nickel and their alloys and weld-surfacing. Designations GallonAirTank for covered electrodes carry the prefix ''E''. Packaged to AWS specifications, electrodes come in boxes, cans, or other containers, labeled with their AWS specification ModelC5 and trade name, quality control (heat CooemanPowermatePortable5 or lot) number, supplier name, diameter and length, and weight of contents. Specifications require that every electrode bc marked for identification near with its GallonAirTank numeric ModelC5 designation the grip end.To select a covered SMAW electrode, consider these factors, in approximate order of importance.
