DIPTI METAL INDUSTRIES
DIPTIINOX® ER308LSi TIG Rod (AWS A5.9): Leading Manufacturer & Exporter for High-Weldability Stainless Steel
Dipti Metal Industries is a Leading ER308LSi TIG Rod Manufacturer and High-Silicon Low-Carbon Welding Wire Exporter in Mumbai, India, specializing in high-performance AWS A5.9 ER308LSi GTAW filler metal under the DIPTIINOX® brand. This solid wire maintains the **0.03% maximum carbon content** of ER308L for intergranular corrosion resistance but features a higher controlled silicon (Si) level of 0.65% to 1.0%. The increased silicon dramatically improves the **weldability**, enhancing the fluidity, wetting action, and allowing for **higher welding speeds** than standard 308L. ER308LSi is ideal for welding Type 304L and 308L in applications requiring superior bead profile and efficient multi-pass welding. As a trusted Stainless Steel TIG Rod ER308LSi Supplier, we guarantee full conformance to AWS A5.9 for automated and high-speed fabrication globally.
DIPTIINOX® ER308LSi: Maximizing Weld Fluidity and Production Efficiency
The AWS A5.9 ER308LSi TIG Rod is the high-performance evolution of the ER308L grade, tailored for enhanced operability and production efficiency. The intentional increase in **Silicon (Si)**, well above the levels found in standard 308L, significantly lowers the surface tension of the weld puddle. This results in **superior arc stability**, exceptional wetting action, and excellent fluidity, enabling the welder to achieve a much **smoother bead profile** and higher welding speeds—a crucial advantage in mechanized and automatic welding (GMAW/TIG). Like its low-carbon counterpart, ER308LSi also retains the essential **0.03% max carbon** restriction, ensuring the resulting weld metal is resistant to **weld decay** and suitable for corrosive service applications. Dipti Metal Industries manufactures every ER308LSi rod with a clean surface and uniform composition to deliver optimal performance in high-demand, cosmetic, and multi-pass welding applications.

ER308LSi TIG Rod — Frequently Asked Questions
The higher **Silicon (Si) content (0.65%–1.0%)** significantly improves the **fluidity (wetting action)** of the weld puddle, leading to a smoother bead profile, better tie-in at the toe of the weld, and is known to facilitate higher welding speeds in automated processes.
ER308LSi should be chosen when a customer prioritizes enhanced weldability, excellent bead appearance, and higher travel speeds, particularly in automated or semi-automatic welding (MIG/GMAW), while retaining the corrosion resistance of the low-carbon (L) grade.
While ER308LSi is still highly resistant to intergranular corrosion (due to the low carbon), the very high silicon content can sometimes slightly lower resistance to pitting and crevice corrosion compared to low-silicon grades, particularly in extremely aggressive media. For general purpose use, the corrosion resistance is still excellent.
The **improved fluidity and better wetting action** provided by the increased silicon help the molten metal flow evenly and quickly, which is crucial in welding thin-gauge stainless steel to ensure proper fusion and minimize the risk of warping or burn-through.
