Both E71T-11 and E71T-GS are self-shielded flux-cored welding wires, but they have some differences in welding performance and application range.
Let's compare them in detail:
1. Welding Performance:
E71T-11: Suitable for various welding positions, including flat, vertical, and overhead welding. It offers good weld formation and penetration.
E71T-GS: Has better arc stability, especially in vertical and overhead positions, resulting in a more aesthetically pleasing weld bead. Additionally, E71T-GS can maintain stable welding quality even in windy environments.
2. Application Range:
E71T-11: Suitable for welding various carbon steel structures, including thin plates and general structural components.
E71T-GS: In addition to carbon steel structures, E71T-GS is more suitable for welding in outdoor or windy environments, especially for short seams and local repairs.
3. Other Differences:
Mechanical Properties: Both have similar mechanical properties and can meet general welding requirements.
Price: Generally, E71T-GS is slightly more expensive than E71T-11.
Feature | E71T-11 | E71T-GS |
Arc Stability | Good | Excellent |
Weld Formation | Good | Better |
Applicable Position | Multiple positions | Multiple positions, especially for vertical and overhead |
Applicable Environment | Indoor and outdoor | More suitable for outdoor or windy environments |
Applicable Range | Carbon steel structures | Carbon steel structures, short seams, local repairs |
Which welding wire to choose depends on the specific welding requirements.
If you have higher requirements for weld appearance and are welding in a harsh environment, you can choose E71T-GS.
If you are more sensitive to welding costs and do not have particularly high requirements for welds, you can choose E71T-11.
4. When choosing a welding wire, you should also consider the following factors:
*Base material and thickness
*Welding position
*Welding current
*Operating environment
