7024 Welding Rod
If you’re a welder, then you know that the 7024 welding rod is one of the main stick welding rods used to deposit big welds. It’s great for welding thick mild steel and carbon steel in flat & horizontal positions.
So what makes the 7024 welding rod so special?
For one, it’s made of high iron oxide with added iron powder to enhance welding output. The travel speed is high with a 7024 welding rod compared to a 7018 rod.
Additionally, the rod produces very few spatters and easily removable slag, making it well-suited for a cleaner weld.
7024 Welding Rod Uses
The 7024 welding rod is most commonly used for general-purpose weldings, such as repairing big steel parts or joining thick steel with Fillet and Lap Joints.
E7024 has the same mechanical properties as 7018 but with no out-of-position welding capability.
The 7024 welding rod is a versatile and affordable option for :
- Welding Lap joints in shipbuilding, bridges, and structures.
- Fillet welds on flat surfaces with high weld metal deposit.
- Welding of tank bottom plate in oil & gas field.
- It gives high travel speed and hence high welding output.
E7024 welding positions
The main limitation of the E7024 welding rod is the welding positions. E7024 welding rod can only be used for flat and horizontal welding positions.
The reason:
- It produces a high amount of molten weld pool i.e. a big weld puddle. One way it fulfills the prime objective of this rod but on another hand, this makes the 7024 rods not useable for out-of-position welding.
- Handling a big molten weld puddle overhead or vertical is very difficult as the most molten metal will fall down due to gravity.
- The coating element is mainly Iron powder with titania covering which also limits the welding positions to flat & horizontal only for 7024 rods.
Is 7024 a low hydrogen electrode?
No, 7024 is not a low hydrogen electrode. 7024 is a titania base covering rod used for stick welding applications.
The main elements of the 7024 rod covering are:
- Iron powder
- Titanium Dioxide
- Cellulose
- Mica
- Feldspar
- Kaolin
- Potassium Silicate
- Silicon dioxide
7024 welding rod amperage
7024 welding rod requires higher welding amperage and it can be run with DC electrode positive, electrode negative, and AC polarity.
With AC polarity, around 180 -200 amperes are good. For a 1/8” 7024 welding rod, 90- 140 amperes works well.
For a 5/32” 7024 welding rod, 120- 180 amperage is sufficient. Higher welding of around 190- 240 amperes is required for 3/16” 7024 rods.
| Recommended Welding amperage for E7024 electrodes | |
| Rod dia. | Amperage |
| 1/8″ | 90 – 140 |
| 5/32″ | 120 – 180 |
| 3/16″ | 190– 240 |
The “2” in 7024 stands for what?
”2” in 7024 stands for welding positions for this rod as per AWS A5.1 specification. ”2” means that the 7024 welding rod can only be used for flat-horizontal welding positions and not for all position welding like E7018, whereas 1 means all position welding rod.
An E7024 electrode has what % iron powder in its coating?
An E7024 electrode has mainly iron powder base coating. The amount of % iron powder in the E7024 electrode is 60%.
What weld position is E7024 capable of welding in?
E7024 is capable of welding in Flat and Horizontal weld positions. The E7024 welding rod is difficult to use in an overhead welding position due to the high amount of molten weld puddle created by this rod.
If you use the E7024 rod in the overhead position, most of the molten weld metal will fall on you due to gravity. Hence, its use is restricted to flat and horizontal welding positions only.
7018 vs 7024
7018 is a low hydrogen welding rod while 7024 is an iron powder titania base rod. 7018 rod can be used in all-position welding while 7024 can only be used for flat and horizontal welding.
7018 welding rod provides deep weld penetration and can be used for fillet welding as well as groove welding applications while 7024 is used only for fillet welds due to low penetrating arc.
7024 welding slag is easily removable compared to 7018 rods.
7016 vs 7024
Both 7016 and 7024 are stick welding rods for mild steel and carbon steel welding. Both 7024 and 7016 have the same mechanical properties. The main differences between 7016 and 7024 are:
- 7016 is an all-position welding rod while 7024 is only for flat & horizontal.
- 7016 coating is primary low hydrogen potassium while 7024 coating is iron powder titania.
- The weld toughness of 7016 is higher than the 7024 welding rod.
What is 7024 welding rod used for?
The main use of 7024 welding rods is welding big welds. The rod can be used with an AC welder as well as a DC welder making it useable in the field and at home use.
7024 rod is used for welding mainly fillet welds only. The reason is the low power of penetration by 7024 rods. If it is used for fill pass in a groove weld, there is a high risk of lack of fusion in welding.
