The difference between the two most common stick welding rods, when to use each, and technique tips
If you are new to stick welding, you have probably heard about 6013 and 7018. These are the two most common electrodes you will encounter, and knowing when to use each will make a huge difference in your weld quality.
A general-purpose mild steel electrode with a titania coating. Known for easy arc starting and a calm, stable arc.
My take: 6013 is the perfect starter rod. If you are learning to weld, start here. It forgives mistakes and lets you focus on technique without fighting the arc.
| Thickness | Amps |
|---|---|
| 1/16" | 20-40 |
| 3/32" | 40-80 |
| 1/8" | 70-120 |
A low-hydrogen iron powder electrode. Known for high strength welds and excellent for thick material.
My take: 7018 is the rod for serious work. Once you have the basics down, 7018 is what you reach for when the weld actually matters. It produces beautiful beads and strong welds.
| Thickness | Amps |
|---|---|
| 1/8" | 90-140 |
| 3/16" | 130-180 |
| 1/4" | 160-220 |
| Feature | 6013 | 7018 |
|---|---|---|
| Arc | Calm, easy | Slightly harsher |
| Slag | Fast freeze | Fast freeze, easy |
| Bead | Narrow | Wide, smooth |
| Storage | Uncritical | Must stay dry |
| Best for | Thin material | Thick, structural |
| Strength | 60,000 PSI | 70,000 PSI |
Use 6013 when: Welding thin metal, you are a beginner, doing quick repairs, working on hobby projects.
Use 7018 when: Welding thick material, strength matters, you need a cosmetic bead, you have proper storage for rods.
7018 is moisture-sensitive. If it gets wet, you will get porosity. Keep unopened packages sealed. Once opened, use within a few days or store in a rod oven.
6013 is more forgiving but still performs better when dry.
