TOKO E81T1-K2C Flux-Cored Welding Wire
TOKO AWS A5.29 E81T1-K2C, flux cored welding wire is used for high-strength, low-alloy steel welding in low-temperature environments. It supports all-position welding with 100% CO2 shielding gas and DC+ polarity. The wire offers stable arc, minimal spatter, and good toughness down to -60°C, ideal for robust welds.
Key Advantages
- AWS A5.29 Certified: Guaranteed compliance with international welding standards.
- Ultra-Low Temperature Performance: Exceptional -60°C impact toughness for cryogenic applications.
- High Tensile Strength: 560MPa (560 N/mm²) weld metal strength.
- 1.5% Nickel Alloy: Enhances notch toughness in sub-zero environments.
- CO₂ Gas Shielded: Optimized for 100% CO₂ shielding gas (20–25 L/min flow rate).
Performance Advantages
- All-Position Welding: Stable arc performance for vertical, horizontal, and overhead welds.
- Superior Weld Quality: Excellent wetting action and joint tie-in for flawless bead appearance.
- High-Speed Efficiency: Designed for rapid deposition rates without compromising integrity.
- Slag Detachability: Easy slag removal reduces post-weld cleanup time.
Critical Applications
- Offshore structures like drilling rigs in cold climates
- Shipbuilding for vessels in cold waters
- LNG/LPG carriers and storage tanks for cryogenic conditions
- Petrochemical engineering for pipelines and pressure vessels
