GS Welding Wire
The group's main brand; with precise quality control in production, suited to projects where consistent weld quality and export standards are the priority.
- Full compliance with the SG2 standard
- Suitable for industrial and export projects
- Standard spool packaging
Kavir Welding Wire
A cost-effective option for general industrial and workshop use, while maintaining full compliance with the SG2 standard.
- Cost-effective for high-volume orders
- Suitable for workshops and industrial repairs
- Sizes from 0.8 to 1.6 mm
An Economical Choice for General Industrial Use
Kavir welding wire is designed for workshops, industrial repairs and projects with high consumption volumes where cost efficiency matters. Even so, there is no compromise on SG2 and ER70S-6 conformity, and its chemical composition and mechanical properties match the technical specification table on this page exactly.
Kavir is available in sizes of 0.8, 1.0, 1.2 and 1.6 mm, and direct delivery from the factory is available for bulk purchases.
Wire Drawing and Welding Wire Production Process
The production of CO2 welding wire begins with the cold drawing of steel wire rod; a process in which the diameter of the initial wire is reduced over several stages until it reaches the final diameter (0.8 to 1.6 mm). Precise control of force, temperature and drawing speed at each stage determines diameter uniformity, tensile strength and surface quality of the wire.
Next, the wire is copper coated to improve the electrical conductivity of the welding current and to protect the wire against rust during storage and transport. Every stage of this process is quality-controlled in accordance with the SG2 standard.
Premium Grade, Export Ready
GS welding wire is the group's main brand and the chosen product for customers who value consistent quality in every production batch and precise conformity with international standards. This product is also supplied to export markets.
For the full technical specifications, the official GS product catalogue is available.
Sizes and Recommended Applications
Four standard sizes, common to both GS and Kavir.
| Size (mm) | Recommended Amperage | Main Application |
|---|---|---|
| 0.8 | 60 – 150 A | Thin sheet, delicate parts and body work |
| 1.0 | 100 – 220 A | Most widely used size; general structures and industrial production |
| 1.2 | 150 – 280 A | Medium to heavy structures, pipes and profiles |
| 1.6 | 200 – 350 A | Thick semi-automatic welding, heavy production lines |
