Similar to E6012; quieter arc,
smoother bead, cleaner weld
metal, fewer inclusions
Characteristics vary with
supplier. Run at lower current
than for E6012.
Use for single-pass,
high-current, high-speed
welding of groove welds in flat
position horizontal lap joints
and fillet welds in sheet metal.
High iron
oxide,
iron powder
For fillet of groove welds, flat
position, heavy slag, good
sidewall fusion. Use at high
amperages on thick plate.
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.

Low-hydrogen
potassium,
iron powder
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.
Yield strength, 53,000-72,000
lb/in. Ductility high, extra
impact strength and
compositional limits and limits
on moisture and hydrogen.
