High-Alloy Hardfacing CO₂ Welding Wire Overview
In CO₂ gas-shielded welding (CO₂ / MAG), various high-strength welding wires are available and are widely used in engineering machinery and mining equipment.
• High-strength structural welding wire: ≥550–690 MPa, suitable for heavy-duty structural applications.
• Low-alloy high-strength welding wire: Balances high strength with good toughness.
• High-strength + wear-resistant welding wire: Designed for areas subject to abrasion while still requiring toughness.
In practical engineering applications, a combination of high-strength structural welding wire for load-bearing joints and hardfacing welding wire for surface wear resistance is commonly adopted.

For equipment such as excavators and buckets that are subject to frequent abrasion from aggregates, high-alloy wear-resistant welding electrodes and wires are required to significantly enhance wear resistance and service life.
