Description

Sifmig Zero SG3 Copper Free Steel MIG Wire – x 0.8 mm x 15 Kg

Sifmig Zero SG3 is a high-quality MIG wire designed without a copper coating. It is specifically tailored for general fabrication, construction, shipbuilding, tanks and boilers, autobody applications, and especially for robotic and automated processes. This wire is versatile and can be used on a broad range of steels, making it a popular choice in sectors like construction, wind turbine tower fabrication, and car manufacturing.

Features & Benefits:

  • Copper-Free: Manufactured without a copper coating, ensuring a cleaner deposit and eliminating the metallurgical risks of increased copper in the weld pool.
  • Versatile Application: Suitable for mild steels, structural steel, fine-grain steel, pipe steel, boiler steel, and cast steel.
  • Enhanced Composition: Increased manganese and silicon content offers improved mechanical properties.
  • High-Quality Finish: The uncoppered finish ensures better feeding, conductivity, and typically provides a higher ultimate tensile strength compared to standard SIFMIG SG2.
  • Robust Performance: Ideal for robotic or automated processes due to its arc-stability characteristics and improved feedability. This ensures steady and uniform welding, reducing potential defects and costly interruptions.
  • Efficient: The wire’s design leads to less post-weld cleanup, minimizing the need for grinding.

Common Applications:

  • Construction: Used in general fabrication and construction projects.
  • Marine: Employed in shipbuilding tasks.
  • Automotive: Popular in car manufacturing industries.
  • Energy: Utilized in wind turbine tower fabrication.
  • Robotic & Automated Processes: Due to its stability and uniformity.
