 3. Welding position. The first performance aor characteristic to consider. compressor High tank and leak cellulose coatings, down 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 aor welds. Also good are rutile-fluxed compressor electrodes-E6012 and E6013--that hold tank out-of-position leak and down weld metal in place aor as it solidifies.4. Welding current. Covered compressor electrodes run on AC, DC, or tank both. When welding DC, the positive lead typically connects to the electrode (DCEP, or reverse polarity). Some suppliers leak design electrodes that weld with the electrode negative (DCEN, or straight polarity). Assure the electrode will perform with the available current. 1. Mechanical properties of the base material. down Tensile aor and compressor strength and yield strength of the weld metal should equal or exceed that of the base material. Ductility and toughness at low temperatures may also be important. tank High-temperature service requires resistance to creep. leak Shock loading requires impact resistance. down In general, weld metal should aor match base-material properties.2. Composition of the base material.For stainless compressor steels, low alloy tank steels, leak nickel and copper down alloys, and materials aor that serve in corrosive atmospheres, chemical composition is important. Consider the possibility of electrochemical corrosion between base and weld metal compressor of different compositions. High-deposition electrodes. These contain iron-powder tank additions in the coating to raise deposition leak and down rate. Designations: EXXX4, EXXX7, EXXX8.For fastest deposition, use the largest diameter possible for an aor application-the thicker the electrode, the compressor greater its current-carrying capacity and the higher the deposition rate. tank and leak and down Welding out of position aor and compressor and overhead, select a small diameter electrode tank and leak to enable welders to reach into down narrow root openings.Gas-Metal-Arc Welding (GMAW, MIG)GMAW typically uses solid wire, spooled or reeled, for continuous feeding to aor the gun; diameter, 0.030 to 1/16 in. compressor typically, although wires as small as 0.020 in. and as large as 1/8 in. are sometimes used. AWS lists specifications tank for filler wires of copper and its alloys, aluminum leak and its alloys, surfacing down and aor alloys, compressor nickel and its alloys, titanium and its alloys, carbon and low tank alloy steels, leak magnesium alloys, and zirconium and its alloys down.
