Welding wire Tysweld T71GS.018 0.8 mm 15 kg flux-cored wire

Tysweld T71GS.018 0.8 mm 15 kg flux-cored wire is a flux-cored welding wire designed for gas-shielded or self-shielded flux-cored arc welding. Supplied on a 15 kg spool with a 0.8 mm wire diameter, this welding wire is intended for welding medium-thickness steel components where deep penetration, stable arc characteristics and high deposition rates are required. The product is suitable for structural steelwork, fabrication and maintenance tasks that demand consistent bead profile and reliable mechanical properties.

Advantages

The flux-cored composition provides strong arc stability and efficient metal transfer, enabling higher welding speeds and reduced operator intervention compared with some solid wires. The 0.8 mm diameter balances access to narrow joint preparations with adequate current-carrying capacity for good penetration. The 15 kg spool format ensures uninterrupted welding for medium-sized jobs and reduces spool changes on production or repair tasks.

Suitable for

• Structural steel welding and fabrication
• Shipbuilding, heavy equipment repair and maintenance
• Welding medium-thickness plates and sections
• Applications requiring deep penetration and high deposition rates
• Gas-shielded or self-shielded FCAW processes

Key specifications

• Wire type: flux-cored welding wire designed for FCAW (gas-shielded or self-shielded)
• Diameter: 0.8 mm
• Spool weight: 15 kg
• Suitable current mode: DC with polarity and parameter settings per manufacturer recommendations
• Typical use: medium-thickness carbon and low-alloy steel

How to use

Prepare weld surfaces by removing rust, scale, oil and contaminants to ensure sound fusion. Load the 15 kg spool onto a compatible wire feeder and set drive rolls and contact tube to match the 0.8 mm diameter. Select appropriate welding parameters (wire feed speed, voltage and travel speed) for the plate thickness, joint configuration and shielding method. For gas-shielded operation, use the recommended shielding gas and flow rate; for self-shielded operation, follow safety and preheat recommendations for the base metal. Maintain consistent contact tip-to-work distance and travel technique to achieve a uniform bead and penetration.

Usage recommendations

Store the spool in a dry environment to prevent moisture pickup. For best results, consult welding procedure specifications (WPS) and perform test welds to fine-tune parameters for the specific base metal, joint geometry and service requirements. Use appropriate personal protective equipment and ventilation when welding with flux-cored wires.
