Description
Weld Star – SG3 (G4Si1) Wire (0.8mm) 15kgÂ
Weld Star SG3 is a copper-coated wire designed for single or multiple welding of carbon-manganese steels. With a higher Si-Mn content, it not only strengthens the weld metal but also ensures a pleasing bead appearance. Its precision layer winding ensures superior wire feeding characteristics, making it suitable for various welding applications.
Features & Benefits:
- Copper Coated: Enhances conductivity and ensures smooth welding.
- Higher Si-Mn Content: Strengthens the weld metal and provides a good bead appearance.
- Versatile: Suitable for single pass or multipass welding of unalloyed and low-alloyed carbon-manganese steels.
- Applications: Ideal for semi-automatic and full-automatic GMAW applications.
- Cold Resistant: Offers good mechanical properties even at sub-zero temperatures down to -40°C.
- Packaging: Comes in vacuum-sealed aluminium foil packaging to prevent moisture absorption.
- Consistent Quality: Produced using virgin raw materials sourced from specialized steel mills.
Common Applications:
- Metal Types: Suitable for carbon-manganese steels.
- Specific Uses: Boilers, industrial machinery, bridges, shipbuilding, automotive, rail, structural and engineering fabrications, etc.
