Description
Weld Star – A18 (ER 70S-6) TIG Wire (2.4mm) 5kg – Min Qty 2
GeKa – A18 TIG Wire is a copper-coated wire designed with high levels of manganese and silicon. This unique composition offers stronger deoxidizing power, especially in situations where rigorous cleaning is not feasible. The wire’s high silicon content enhances the fluidity of the weld pool, leading to a smoother bead appearance and reducing the need for post-weld grinding.
Features and Benefits:
- Strong Deoxidizing Power: Contains high levels of manganese and silicon, making it ideal for situations where stringent cleaning isn’t possible.
- Smooth Welds: The high silicon content ensures a smoother bead appearance, minimizing post-weld grinding.
- Cold Weather Performance: Offers good mechanical properties even at sub-zero temperatures down to -40°C.
- Versatile Applications: Suitable for a range of applications including boilers, industrial machinery, bridges, shipbuilding, automotive, rail, and various structural and engineering fabrications.
- Quality Production: Manufactured using virgin raw materials from specialized steel mills, guaranteeing consistent quality and reliability.
Common Applications:
- Boilers & Pressure Vessels: Ideal for welding boilers and other pressure vessels.
- Infrastructure: Suitable for constructing bridges and other structural fabrications.
- Shipbuilding: Used in shipbuilding applications.
- Industrial Machinery: Perfect for welding various industrial machinery and equipment.
