TIG welding rods 308LSi are designed for welding austenitic stainless steels such as AISI 304, 304L, and their equivalents. The “L” indicates low carbon content, which minimizes the risk of intergranular corrosion, while the added silicon (Si) improves arc stability, weld pool fluidity, and overall weld appearance.

These rods are ideal for applications requiring high corrosion resistance and excellent weld quality, particularly in the food industry, chemical processing, pharmaceuticals, and architectural structures. The enhanced silicon content also improves wetting behavior, making 308LSi filler rods perfect for smooth, spatter-free welds with minimal post-weld cleaning.

Suitable for TIG (GTAW) welding using argon shielding gas, 308LSi rods provide bright, smooth welds with good mechanical properties and excellent resistance to oxidation at elevated temperatures.

Because of their versatility and reliable performance, they are widely used in manufacturing tanks, piping, kitchen equipment, stainless steel furniture, and structural components made from 18/8 stainless steels.
