E71T-1 is a gas-shielded, flux-cored welding wire for mild and low-alloy steels, known for its all-position capability (flat, horizontal, vertical, overhead), smooth arc, low spatter, and easy slag removal, making it ideal for construction, shipbuilding, and general fabrication. It provides strong welds with good mechanical properties, typically requiring a 75-80% Argon/20-25% CO2 gas mixture, though 100% CO2 can also be used.
Key Characteristics & Benefits
Type: Gas Shielded Flux-Cored (FCAW).
Material: Used for welding carbon and low alloy steels with a minimum tensile strength of 71,000 psi (490 MPa).
Performance: Offers a soft, stable arc, excellent feedability, low spatter, and a smooth bead appearance.
Slag: Features a rutile-based slag that is easy to remove, reducing cleanup time.
Positions: Suitable for single and multiple-pass welding in all positions.
Shielding Gas: Works with Argon/CO2 mixtures (e.g., 75% Ar/25% CO2) or 100% CO2.
