5. Joint design and material thickness. air Some electrodes create an arc that penetrates tqnks deeply, performing well on thick sections with narrow compressors grooves or no air bevel. Poor fit-up calls for electrodes that can bridge wide gaps.6. Efficiency. Meeting all other conditions, engineers select the electrode that gives highest deposition tqnks rate. For heavy-section joints, use powder-metal-addition fillers.Designating electrodes for carbon and low-alloy steels, following the prefix compressors E'', to signify a SMAW electrode, come air two or three digits to indicate minimum tensile strength in 1,000 PSI units; a digit indicating usable current and electrode-coating type; and, in some cases, a hyphen followed by a letter and number suffix to denote tqnks weld metal composition. Example: E7010-A1 is a SMAW electrode (E), of 70,000-psi tensile strength (70), for use in all welding positions (1), having a high-cellulose-sodium coating tin use with DCEP compressors (0). -A1 air indicates a particular composition listed in the A5 specification. A-1 suffix, as in 7018-1, indicates high impact toughness at a temperature lower than specified for a standard E7018 electrode.

3. Welding position. The first performance characteristic to tqnks consider. High cellulose coatings, like those on E6010 and E6011 electrodes, generate a light slag that makes for rapid solidifying of the weld metal good for-out-of-position compressors welds. Also good are rutile-fluxed electrodes-E6012 air and E6013--that hold out-of-position 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 tqnks with the available current.

High-deposition electrodes. These contain iron-powder additions in the coating compressors and air to raise deposition rate. Designations: EXXX4, EXXX7, EXXX8.For fastest deposition, use the largest diameter possible for an application-the thicker the electrode, tqnks the greater its current-carrying compressors capacity and the higher the deposition rate. Welding air and tqnks out of position and overhead, select a small diameter electrode to enable welders to reach into narrow root openings.Gas-Metal-Arc Welding (GMAW, MIG)GMAW typically uses solid wire, spooled or reeled, for continuous feeding to the gun; diameter, 0.030 to 1/16 in. typically, although wires as small as 0.020 in. and as large as 1/8 in. are sometimes used. AWS lists specifications compressors for filler wires of copper and its alloys, aluminum air and its alloys, surfacing alloys, nickel and its alloys, titanium and its alloys, carbon and low alloy steels, magnesium tqnks alloys, and compressors zirconium and its alloys.
