Product Details

Our Wear-Resistant Surfacing Cored Wire is a premium tubular welding consumable engineered for high-efficiency surfacing and hard-facing applications. Utilizing a specialized manufacturing process where a low-carbon or low-alloy steel strip is rolled into a U-shape and filled with precision-dosed welding powder, this flux-cored wire delivers exceptional plasticity and structural integrity. Available in both gas-shielded and self-shielded configurations, it is designed to provide superior protection against abrasion and wear in the most demanding industrial environments.

Specifically optimized for carbon steel and low-alloy structural steel with tensile strengths exceeding 490MPa, our cored wires—including the E70T-1 and E71T-1 models—are indispensable for the shipbuilding and heavy machinery industries. By offering tailored slag systems (acidic for all-position versatility and basic for high-purification flat/fillet welding), we ensure that every weld bead achieves maximum mechanical performance, durability, and corrosion resistance.

Frequently Asked Questions

Q: What is the difference between gas-shielded and self-shielded flux-cored wire?

Gas-shielded wires require an external shielding gas (like CO2 or Argon mix) to protect the weld pool, while self-shielded wires contain ingredients that generate their own protecting gas during welding.

Q: Which model should I choose for shipbuilding applications?

For shipbuilding, the acid slag flux-cored wire (such as our E70T-1) is highly recommended due to its excellent all-position welding performance and high efficiency.

Q: What are the mechanical benefits of the basic slag system?

The basic slag system provides a superior purification effect on the weld metal, making it ideal for flat and fillet welding where high strength and purity are critical.

Q: Is this wire suitable for low-temperature environments?

Yes, our CB E70T-1 and E71T-1 models maintain an impact value (KV2) of ≥ 27J even at -20°C, ensuring toughness in cold climates.

Q: What base materials can be welded with these cored wires?

These wires are specifically designed for carbon steel and low-alloy structural steels with a tensile strength of 490MPa or higher.

Q: What current settings are recommended for the best results?

We recommend using DC+ (Direct Current Positive) to achieve the best arc stability and penetration for these specific cored wire models.
