Description
Weld Star – SG2 (G3Si1) Wire (0.6mm) 15kg (Plastic)
Weld Star SG2 is a copper-coated solid wire designed for both single pass and multipass welding of unalloyed and low-alloyed carbon-manganese steels. With a diameter of 0.6mm and a weight of 15kg, this wire is packaged in a vacuum-sealed plastic bag to prevent moisture absorption, ensuring the wire remains in optimal condition for welding. It offers good mechanical properties even at sub-zero temperatures, reaching as low as -40°C.
Features & Benefits:
- Copper-Coated: Provides smooth feeding and consistent welding performance.
- Sub-Zero Performance: Retains good mechanical properties even at temperatures as low as -40°C.
- Vacuum-Sealed Packaging: Ensures the wire remains free from moisture and in optimal condition.
- Precision Layer Wound: Guarantees superior wire feeding characteristics for a smooth welding experience.
- High-Quality Raw Materials: Produced using virgin materials from specialized steel mills for consistent quality and reliability.
- Alignment Hole Clip: Ensures smooth and consistent wire feeding.
Common Applications:
- Industrial Machinery: Ideal for welding parts and components of heavy machinery.
- Construction: Suitable for structures like bridges and buildings.
- Transportation: Used in shipbuilding, automotive manufacturing, and the railway industry.
- Boilers & Pressure Vessels: Ensures strong and durable joints.
- General Fabrications: Perfect for various structural and engineering fabrications.
The Weld Star SG2 wire is a top choice for professionals in need of a reliable and high-quality welding solution, especially for projects that require strength and durability even in cold environments.
