| 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. |
