Weld Star - SG2 (G3Si1) Wire (0.6mm) 5kg

Features and Applications
A copper-coated solid wire suitable for single-pass or multipass welding of unalloyed and low-alloyed carbon-manganese steels.

Good mechanical properties at sub-zero temperatures down to -40ºC.

Precision layer wound for superior wire feeding characteristics.

Typically used on boilers, industrial machinery, bridges, shipbuilding, automotive, rail, structural and engineering fabrications etc.

Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.
