Description
Sifmig Zero SG3 Copper Free Steel MIG Wire – x 1 mm x 18 Kg
Sifmig Zero SG3 is a double-deoxidised mild steel MIG wire, distinctively free from copper coating. It’s designed for welding unalloyed and low-alloyed mild and medium tensile steels. With its high-quality uncoppered finish, it ensures improved feeding and conductivity. This wire is specifically manufactured to provide a cleaner deposit, eliminating the metallurgical risks associated with increased copper in the weld pool.
Features & Benefits:
- Copper-Free Coating: Ensures a cleaner deposit and reduces metallurgical risks.
- High-Quality Uncoppered Finish: Offers improved feeding and conductivity.
- Enhanced Composition: Contains increased silicon and manganese for improved mechanical properties.
- Arc-Stability: Ideal for robotic or automated processes ensuring steady and uniform welding.
- Reduced Cleanup: Minimizes post-weld cleanup and grinding, saving time and effort.
Common Applications:
- General fabrication
- Construction and shipbuilding
- Tanks and boilers
- Autobody applications
- Robotic and automated processes
- Suitable for a range of steels including mild steels, structural steel, fine-grain steel, pipe steel, boiler steel, and cast steel. It’s especially popular in the construction sector, wind turbine tower fabrication, and car manufacturing industries.
