The Weld Star ER80S-G Corten TIG Wire is a copper-coated TIG (GTAW) filler wire specifically formulated for welding Corten (weathering) steels and other high-strength low-alloy (HSLA) materials. Designed to deliver robust mechanical properties and enhanced atmospheric corrosion resistance, this wire produces smooth, clean welds with consistent performance in fabrication, structural, maintenance and outdoor applications.
Manufactured from high-quality virgin raw materials, the ER80S-G filler ensures dependable weld metal composition and reliable joint strength - ideal for projects where both integrity and durability are required.
Key Features
ER80S-G Classification: Designed for TIG welding of Corten (weathering) steels and HSLA materials, with chemical composition and deoxidisers optimised for this application.
Copper-Coated Finish: Enhances wire feeding and TIG arc stability, producing smooth weld beads with minimal spatter and excellent appearance.
Atmospheric Corrosion Resistance: Weld metal formulated to match or complement the corrosion resistance of weathering steels, making it suitable for exposed steelwork.
Strong Mechanical Properties: Provides high tensile and yield strength suitable for structural and outdoor fabrication. Typical weld metal offers a durable balance of strength and ductility.
Good Weld Quality: Designed to deliver good fusion with base metals and clean weld characteristics under TIG processes.
Shielding Gas: Recommended for use with 100 % argon (I1 per EN ISO 14175) for stable arc behaviour and weld protection.
Industry Standards: Meets relevant international TIG filler classifications for ER80S-G quality and performance.
Workshop-Friendly Packaging: Supplied on 5kg spools with common TIG diameters 2.40mm and 3.20mm; each spool 1000mm in length.
