Sifmig Zero SG3 Copper Free Steel MIG Wire 18kg

Description

Sifmig Zero SG3 Copper Free Steel MIG Wire 18kg

Sifmig Zero SG3 is a double-deoxidised mild steel MIG wire, devoid of any copper coating. It is enriched with increased silicon and manganese content, making it ideal for welding unalloyed and low-alloyed mild and medium tensile steels. This wire is especially suitable for applications that demand good impact toughness even at temperatures as low as -20°C.

With its high-quality uncoppered finish, it ensures improved feeding and conductivity.

Compared to the standard SIFMIG SG2, the ZERO SG3 typically offers a superior ultimate tensile strength.

Features & Benefits:

• Copper-Free: Ensures a cleaner deposit and eliminates the metallurgical risks associated with increased copper in the weld pool.
• Enhanced Conductivity: Manufactured with a high-quality uncoppered finish for better feeding and conductivity.
• Arc-Stability: Exhibits excellent arc-stability characteristics, making it perfect for robotic or automated processes.
• Reduced Clean-up: The wire’s properties lead to fewer welding defects, minimizing expensive cycle interruptions and reducing post-weld clean-up and grinding.

Common Applications:

• Versatile Use: Ideal for general fabrication, construction, shipbuilding, tanks and boilers, and autobody applications.
• Robotic & Automated Processes: Its arc stability and feedability make it suitable for these applications.
• Material Compatibility: Can be used on a range of materials including mild steels, structural steel, fine-grain steel, pipe steel, boiler steel, and cast steel. It is especially popular in sectors like construction, wind turbine tower fabrication, and car manufacturing.
