Walid Stainless, located in Tunis, Tunisia, has built a solid reputation as a reliable manufacturer and supplier of top-notch welding consumables, including specialized filler metals for both MIG and TIG welding. One of their standout products is the **AWS Class ER308LSi MIG and TIG filler welding wire and rod**, designed to deliver exceptional weld quality, impressive arc stability, and smooth metal transfer when working with austenitic stainless steels. This filler metal is crafted to improve fluidity and wetting, resulting in clean, uniform weld beads with minimal spatter. Walid Stainless is committed to strict quality control and follows international standards, catering to industries like chemical processing, food and beverage, marine, power generation, and construction, where dependable performance and corrosion resistance are crucial.
The AWS Class ER308LSi MIG and TIG fillers are austenitic stainless steel consumables made primarily of iron, chromium (19–21%), nickel (9–11%), and a deliberate addition of silicon (usually 0.5–1%) to enhance weld pool fluidity and arc characteristics. With a low carbon content, these fillers help minimize the risk of carbide precipitation, boosting resistance to intergranular corrosion. Mechanically, weld metal produced with ER308LSi filler typically boasts a tensile strength of around 75 ksi (515 MPa) along with good elongation and toughness, ensuring durable, crack-resistant joints in service.
