Description
Weld Star – SG3 (G4Si1) Wire (1.2mm) 15kgÂ
Weld Star – SG3 (G4Si1) Wire is a copper-coated solid wire designed specifically for welding low-alloyed and unalloyed carbon-manganese steels. With an increased Si-Mn content, it offers enhanced weld metal strength, resulting in a visually appealing bead appearance. The wire is precision layer wound, ensuring superior wire feeding and consistent welding results. Its ability to maintain good mechanical properties even at sub-zero temperatures (as low as -40°C) makes it a versatile choice for various applications.
Features & Benefits:
- Copper Coated: Ensures smooth and consistent welding.
- Higher Si-Mn Content: Provides increased weld metal strength and an attractive bead appearance.
- Precision Layer Wound: Guarantees superior wire feeding characteristics.
- Sub-Zero Mechanical Properties: Maintains strength and durability even at temperatures as low as -40°C.
- Vacuum-Sealed Packaging: Aluminium foil packaging prevents moisture absorption, ensuring the wire remains in optimal condition.
- Green Wire: Produced using virgin raw materials from specialized steel mills, ensuring consistent quality and reliability.
Common Applications:
- Boilers & Industrial Machinery: Ideal for creating durable joints and welds.
- Construction: Suitable for welding bridges and other structural components.
- Transportation: Used in shipbuilding, automotive, and railway sectors.
- Engineering Fabrications: Provides strong and resilient welds for various engineering projects.
- Others: Including structural steelwork, wind turbine tower fabrication, and car manufacturing industries.
The wire complies with EN ISO 14341-A and AWS A5.18 standards, ensuring it meets industry benchmarks for quality and performance.
