Arcflow 70S-2 Carbon Steel Filler Wire (ER70S-2) is a high-quality welding consumable used for welding mild steel and carbon steel components in fabrication, construction, and industrial manufacturing. The wire conforms to AWS A5.18 ER70S-2 classification, ensuring reliable welding performance and consistent weld quality.
This filler wire contains multiple deoxidizing elements such as titanium, zirconium, and aluminum, along with manganese and silicon. These elements help remove impurities during welding and allow the wire to perform well even on slightly rusty or contaminated surfaces.
Arcflow 70S-2 filler wire provides smooth arc stability, controlled weld puddle, and minimal spatter, enabling welders to achieve clean weld beads with strong mechanical properties. The weld metal typically delivers a minimum tensile strength of around 70,000 psi, ensuring durable and reliable welded joints for demanding industrial applications.
This filler wire is widely used in TIG (GTAW) and MIG (GMAW) welding processes and is suitable for welding pipes, tubing, structural steel, pressure vessels, and sheet metal components. Its excellent weldability and high-quality weld deposits make it a preferred choice for professional welders and fabrication industries.
