242201184 - Esab Dual Shield R-70 Ultra E70T-1 Flux-Cored Wire .045

High-Performance Flux-Cored Wire for Industrial Applications

The Esab Dual Shield R-70 Ultra is a premium gas-shielded flux-cored wire designed to meet the rigorous demands of heavy industrial welding. Classified as an E70T-1 electrode, this wire is engineered specifically for welding low and medium carbon steels in the flat and horizontal positions. It is the ideal choice for fabricators looking to maximize deposition rates while maintaining high weld quality.

One of the standout features of the R-70 Ultra is its specialized formulation which provides exceptional tolerance to surface contaminants. It handles mill scale, rust, and oxides far more effectively than standard wires, ensuring sound welds even on less-than-perfect base materials. This makes it a go-to solution for structural steel projects where surface preparation time is limited.

The wire is designed to operate exclusively with 100% CO2 shielding gas, which offers deep penetration and cost-effectiveness. The arc characteristics are smooth and stable, producing a flat to slightly convex bead profile that ties in smoothly at the toes. Additionally, the slag system is designed for easy detachment, often peeling off by itself, which significantly reduces post-weld cleaning and grinding time.

Whether used for single-pass fillets or multi-pass heavy plate welding, the Esab Dual Shield R-70 Ultra delivers consistent mechanical properties, including improved strength and toughness in the as-welded condition. It is widely utilized in civil construction, railcar manufacturing, and ship building.
