AK-E71T-11 Flux-Cored Wire for All-Position Carbon Steel Welding.
A self-shielded flux-cored wire with stable arc, low spatter, and easy slag removal, suitable for multipass welding and vertical-down applications on carbon steel sheet structures.
Product Overview
AK-E71T-11 is a self-shielded flux-cored wire designed for all-position welding of carbon steel sheet structures. It supports multipass welding and can be used in vertical-down welding positions.
The wire delivers good welding performance with low spatter, stable arc, low fume emission, and easy slag removal, resulting in a clean, well-shaped bead appearance.
Application: Used to weld carbon steel sheet structures.
Key Benefits
Stable Arc and Low Spatter.
The flux-cored formulation ensures a stable arc across the recommended current range, reducing spatter and improving weld consistency during manual welding operations.
Easy Slag Removal
Slag produced during welding lifts off easily without requiring extensive chipping, reducing inter-pass cleaning time and minimizing the risk of slag entrapment.
Excellent Bead Appearance
The wire produces a smooth, uniform bead profile with minimal surface irregularities, reducing the need for post-weld grinding or finishing.
All-Position and Vertical-Down Capability.
Suitable for flat, horizontal, vertical, and overhead positions, including vertical-down welding, allowing continuous welding without changing consumables.
Where It Is Used
- Carbon steel sheet structures in fabrication and assembly.
- Multipass welding in structural steel and general fabrication.
- Vertical-down welding in construction and maintenance.
- Applications requiring low fume and clean weld appearance.
Who It Is For
- Welding consumable distributors supplying flux-cored wires for structural applications.
- Steel fabricators working with carbon steel sheets and requiring high productivity.
- Maintenance teams performing vertical-down welding in field or shop environments.
Problems It Solves
- Inconsistent weld quality and excessive spatter when using flux-cored wires with unstable arcs.
- Difficult slag removal and inter-pass cleaning due to stubborn or adherent slag.
- Limited position flexibility requiring multiple wire types for different joint orientations.

Technical Features
- Self-shielded flux-cored wire for all-position welding, including vertical-down.
- Chemical composition: C ≤0.18%, Si ≤0.90%, Mn ≤1.75%, S ≤0.03%, P ≤0.03%
- Supplied in 0.8 mm, 0.9 mm, and 1.0 mm diameters.
- Meets EN ISO 17632-A: T46 Z V N 1, AWS A5.20 E71T-11, and GB/T 10045 E501T-11 standards.
Use Guide
- Select wire diameter based on joint thickness and welding position: 0.8 mm, 0.9 mm, or 1.0 mm.
- Set voltage between 15 V and 20 V, and current between 80 A and 150 A for all diameters.
- Ensure joint surfaces are clean and free from oil, rust, paint, and moisture before welding.
- Use proper shielding gas if required by the application, though the wire is self-shielded.
- Store wire in dry conditions and avoid exposure to moisture; re-dry if necessary before use.
How It Compares
AK-E71T-11 and E71T-1B both weld carbon steel in all positions, but E71T-11 is self-shielded and does not require external gas, making it suitable for field use. E71T-1B requires shielding gas and is typically used in controlled environments. E71T-11 offers lower fume and better slag removal than some other flux-cored wires, improving welder comfort and productivity.
