Description
Weld Star – SG2 (G3Si1) Wire (1.2mm) 15kg
Weld Star SG2 (G3Si1) Wire, with a diameter of 1.2mm and weighing 15kg, is a copper-coated solid wire. It’s designed for both single pass and multipass welding and showcases impressive mechanical properties even at sub-zero temperatures reaching -40°C.
Features:
- Copper-Coated: Ensures smooth welding and reduces the risk of rusting.
- Versatility: Suitable for both single pass and multipass welding.
- Packaging: Comes in a vacuum-sealed plastic bag to prevent moisture absorption.
- Alignment Hole Clip: Ensures smooth feeding during the welding process.
- Precision Layer Wound: Guarantees superior wire feeding characteristics.
- Quality Assurance: Produced using virgin raw materials from specialized steel mills
- Cold Resilience: Maintains good mechanical properties even at temperatures as low as -40°C.
- Broad Applications: Ideal for use on boilers, industrial machinery, bridges, shipbuilding, automotive, rail, structural, and engineering fabrications.
- Consistent Quality: The use of virgin raw materials ensures reliability and consistent quality.
Common Applications:
This wire is typically employed in a variety of sectors, including boilers, industrial machinery, bridges, shipbuilding, automotive, rail, and other structural and engineering fabrications.
