Vinit Stainless is a well-respected manufacturer and supplier of AWS Class ER309LSi MIG and TIG Filler Welding Wire and Rod, proudly based in Chennai, India. The ER309LSi filler metal is specifically designed for welding different types of metals, particularly stainless steels to carbon or low-alloy steels, and for creating corrosion-resistant overlays on mild steel. Thanks to its higher silicon content, it enhances the fluidity of the weld pool and improves the appearance of the bead. Plus, the low carbon content helps reduce carbide precipitation, boosting resistance to intergranular corrosion. Manufactured to meet strict AWS standards, our ER309LSi wires and rods provide smooth, spatter-free welds with outstanding mechanical properties, making them ideal for critical fabrication and repair work.
AWS Class ER309LSi MIG and TIG filler rod welding wires are designed for welding dissimilar metals, such as stainless steel to carbon steel. These rods typically contain 24-26% chromium and 13-15% nickel. With a high silicon content (up to 0.65%) to improve the hydration and appearance of the weld pool Silicon enhancement helps reduce spatter and bead is firmly established. The ER309LSi provides a durable corrosion-resistant weld suitable for applications. In power generation, petrochemical industries, and architectural construction, and ensures high-quality, durable joints.
