E7018 vs E71T-11: Stick Rod vs Flux-Core Wire Comparison
E7018 is the standard code-quality stick rod. E71T-11 is self-shielded flux-core wire for faster outdoor welding. Different processes, different strengths.
Key Differences
| Attribute | E7018 | E71T-11 |
|---|---|---|
| Difference 1 | E7018 is stick welding (SMAW) with low-hydrogen properties meeting D1.1 code | |
| Difference 2 | E71T-11 is flux-core (FCAW-S) with faster deposition but not low-hydrogen | |
| Difference 3 | E7018 requires more operator skill | E71T-11 is semi-automatic |
| Difference 4 | E7018 needs rod storage discipline | E71T-11 does not |
Use E7018 when:
Code-quality structural welding. D1.1 and pressure vessel work. Pipe welding. When WPS specifies stick. When you need low-hydrogen properties. Tight spaces where a MIG gun does not fit.
Use E71T-11 when:
Non-code fabrication where speed matters. Outdoor and field welding. Farm and ranch repair. Long continuous welds where stick rod changes slow you down. When you have a wire feeder available.
How E7018 and E71T-11 Work Together
E71T-11 can deposit 2-3x the metal per hour compared to E7018 stick. But E7018 produces mechanically superior welds with low hydrogen and better notch toughness. The choice depends on whether the application demands code-quality properties.
Common Mistake With E7018
Assuming E71T-11 is a direct substitute for E7018 on code work. It is not low-hydrogen and most D1.1 WPS require stick or gas-shielded flux-core, not self-shielded.
