SMAW · Carbon steel
E7024
A heavy iron powder production rod that is dragged along the joint on its covering, laying long flat fillets faster than any all-position carbon steel electrode.
What the designation means
Point at any character to see what it claims. The classification is a sentence written in fields, not a product name.
- EElectrode for shielded metal arc welding.
- 7070,000 psi minimum tensile strength of the weld metal.
- 2Limited to the flat position and horizontal fillets, not all positions.
- 4Iron powder titania covering with a heavy iron powder loading, run on alternating current or either direct current polarity.

Typical uses
- Long horizontal fillet welds on structural members
- Flat position plate fabrication in a shop fixture
- Repetitive production welds where deposition rate drives cost
How it runs
- Very high deposition rate from the iron powder in the covering
- Shallow penetration with a wide, fluid puddle
- Heavy self-lifting slag that often pops off in one piece as it cools
- Smooth, flat, almost mechanical bead appearance
Storage and handling
Ordinary dry storage; the covering is not moisture controlled, but wet rods lose the drag characteristic and trap slag.
Compare with
SMAWE7014A rutile rod with iron powder in the covering, so it deposits noticeably faster than a plain general purpose rod while keeping the same easy, forgiving arc.SMAWE7028A low-hydrogen rod built for downhand production, combining moisture-controlled weld metal with the deposition rate of a heavy iron powder covering.SMAWE6022A high-speed production rod for single-pass lap and fillet welds on sheet and light plate, laying a wide flat bead at travel speeds a general purpose rod cannot match.
