The Weld Star ER80S-Ni1 TIG Wire is a high-quality nickel-enriched low-alloy filler wire designed for TIG (GTAW) welding of structural and high-strength steels. The “Ni1” designation indicates controlled nickel content, enhancing weld metal toughness, ductility and overall performance - particularly beneficial where impact resistance, weld integrity and mechanical strength are priorities.
This wire is engineered for professional applications needing reliable TIG performance, strong weld deposits and smooth bead appearance, making it suitable for boilers, pressure vessels, industrial structures and general fabrication where high-strength low-alloy steels are used.
Manufactured from high-quality raw materials for consistent results, this filler wire is supplied on workshop-friendly spools.
Key Features
Nickel-Enriched Low-Alloy Filler: The controlled nickel content enhances weld metal mechanical properties compared with standard low-alloy wires.
High Mechanical Strength: Produces strong tensile and yield properties in welded joints, ideal for demanding structural and pressure applications.
Enhanced Toughness & Ductility: Nickel addition improves weld-metal impact performance — useful where material toughness is needed at varied temperatures.
Good Weldability: Designed for TIG welding with stable arc behaviour and smooth bead appearance, requiring minimal cleanup.
Versatile Steel Compatibility: Suited to structural, pressure vessel, boiler plate and other low-alloy steels where nickel-enhanced filler improves performance.
Shielding Gas: Best results when used with 100 % argon (I1 per EN ISO 14175) for reliable TIG arc protection.
Standards Compliance: Meets recognised TIG consumable classifications for ER80S-Ni1, ensuring predictable chemical and mechanical performance.
Workshop-Friendly Packaging: Supplied on 5kg spools with common TIG diameters 1.60mm, 2.40mm and 3.20mm; each spool 1000mm in length.
