HH-CE71T-1 Flux Cored Wire for Shipbuilding Welding
Key Features
1.High Deposition Rates: Flux-cored wires typically offer 15-30% higher deposition rates compared to solid wires, significantly improving productivity.
2.All-Position Welding Capability: Certain types (especially gas-shielded varieties) enable welding in vertical and overhead positions.
3.Excellent Arc Stability: The flux composition helps maintain a stable arc even in windy outdoor conditions.
4.Self-Shielding Options: Some wires contain compounds that generate protective gases when heated, eliminating the need for external shielding gas.
Types of Flux-Cored Wires
|
Gas-Shielded (FCAW-G) |
Requires external CO₂ or mixed gas protection; produces cleaner welds with less spatter (e.g., AWS E71T-1). |
|
Self-Shielded (FCAW-S) |
Contains gas-forming elements in the flux; ideal for outdoor/windy environments (e.g., AWS E71T-8). |
|
Stainless Steel Variants |
For corrosion-resistant applications (e.g., E308LT1-1). |
|
Metal-Cored Wires |
Hybrid design with metallic powder fillers for higher deposition and cleaner welds. |
Technical Advantages
Deep Penetration: The flux composition allows for better penetration than solid wires.
Slag Formation: The protective slag layer must be removed after welding but helps shape the weld bead.
Tolerance to Surface Contaminants: More forgiving on lightly rusted or painted surfaces compared to MIG welding.
Products features

Common Applications
Structural steel erection in high-rise buildings
Ship hull fabrication and repairs
Heavy machinery manufacturing
Pipeline construction (particularly in field conditions)
Pressure vessel fabrication
Process Considerations
1.Wire Selection: Choose between rutile (smooth arc) or basic (high toughness) flux types based on application requirements.
2.Shielding Gas: When using gas-shielded types, 75% Ar + 25% CO₂ is common for carbon steel.
3.Parameters: Typically operates at higher currents than solid wires (e.g., 1.2mm wire at 180-280A).
Comparison with Other Processes
vs. SMAW: Faster deposition, less electrode changing.
vs. GMAW: Better outdoor performance, higher deposition.
vs. SAW: More portable but with lower deposition rates.
Conclusion
Flux-cored welding wire represents an optimal balance between productivity and versatility, particularly valuable in field applications requiring high deposition rates and tolerance to environmental variables. Proper selection of wire type and parameters can deliver high-quality welds across a broad range of industrial applications.
