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.

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
