Ultra high-strength MIG wire designed for critical applications — excellent toughness, smooth feeding, and dependable performance down to -40°C.
Weld Star ER 110S-G is a copper-coated NiCrMo alloyed MIG wire developed for welding high-strength, low-alloy steels requiring superior mechanical properties.
It is suitable for both single and multi-pass welds and performs exceptionally well under demanding structural and environmental conditions.
With tensile strength exceeding 800 MPa and reliable impact toughness down to -40°C, ER 110S-G is ideal for critical fabrication where strength, integrity, and low-temperature performance are essential.
It is precision layer wound to deliver smooth wire feeding, even in automated and long-run applications.
This wire is commonly used across offshore, petrochemical, structural, and heavy machinery industries, and is produced using virgin raw materials from specialised steel mills to ensure consistent quality.
