China Suppliers Factory HH-CE71T-1 Flux Cored Wire for Shipbuilding Welding in Marine Engineering and Construction
Key Features
Flux-cored wires typically offer 15-30% higher deposition rates compared to solid wires, significantly improving productivity.
Certain types (especially gas-shielded varieties) enable welding in vertical and overhead positions.
The flux composition helps maintain a stable arc even in windy outdoor conditions.
Some wires contain compounds that generate protective gases when heated, eliminating the need for external shielding gas.
Types of Flux-Cored Wires
| Type | Description |
|---|---|
| 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
Faster deposition, less electrode changing.
Better outdoor performance, higher deposition.
More portable but with lower deposition rates.
