Covered Electrodes for SMAW of Carbon Steel

Stick Welding	Covered Electrodes for SMAW of Carbon Steel per AWS A5.1 Arc-Welding Processes – SMAW
Classification	Covering	Weld Position	Current	Characteristics, applications
E6010	High-cellulose sodium	F, V, O, H	dcep	A general purpose electrode for joining of carbon steel. Deep-penetrating forceful arc. Thin slag. Us in all positions, single and multiple pass, plate and pipe, galvanized and alloy steels. Ships, bridges, buildings, piping, tanks, pressure-vessel fittings.
E6011	High-cellulose potassium	F, V, O, H	ac, dcep	Similar to E6010, but for use with ac. Dcep gives reduced penetration.
E6012	High-titania sodium	F, V, O, H	ac, dcen	Dense slag that covers the bead, low-penetrating arc. Use to bridge joints with poor fitup. Fillets have smooth convex face. Runs well at amps higher than E6010/E6011.
E6013	High-titania potassium	F, V, O, H	ac, dcen, dcep	Similar to E6012; quieter arc, smoother bead, cleaner weld metal, fewer inclusions Characteristics vary with supplier. Run at lower current than for E6012.
E6022	High iron oxide	F	ac, dcep, dcen	Use for single-pass, high-current, high-speed welding of groove welds in flat position horizontal lap joints and fillet welds in sheet metal.
E6027	High iron oxide, iron powder	H-fillets, F	ac, dcep	For fillet of groove welds, flat position, heavy slag, good sidewall fusion. Use at high amperages on thick plate.
E7014	Iron powder, titania	F, V, O, H	ac, dcep	Iron powder boosts deposition rate and efficiency. Use at high amperages on carbon and low-alloy steels. Low-penetrating arc, use to bridge poor fitups. Smooth, fine-rippled bead, convex fillets.
E7018, 7018-1 7018R 7018-1R 7018H16, H8, H4	Low-hydrogen potassium, iron powder	F, V, O, H	ac, dcep	Iron-powder addition increases deposition rate. Use on carbon, high-carbon, and low-alloy steels. Smooth arc, low spatter. Flat and horizontal welds are finely rippled. Convex. Other types: E7018-1H16R, E7018-1H8R, E7018-1H4R.
E7018M	Low-hydrogen iron powder	F, V, O, H	dcep	Yield strength, 53,000-72,000 lb/in. Ductility high, extra impact strength and compositional limits and limits on moisture and hydrogen. Similar to E7018-1H4R, MIL-7018-M. Characteristics similar to E7018.
E7024 E7024-1	Iron powder, titania	H-fillets, F	ac, dcep, dcen	Iron powder for high deposition rate, high travel speed, flat, smooth fillets, finely rippled. Smooth, quiet arc, low penetration. E7024-1 deposits more-ductile weld metal of improved Charpy values.
