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 ER347 MIG and TIG filler welding wire and rod**, designed specifically for welding stabilized austenitic stainless steels that require exceptional resistance to intergranular corrosion and can handle high temperatures. This filler metal ensures smooth arc stability, clean metal transfer, and consistent weld quality, making it a great choice for both manual and automated MIG and TIG welding processes. Walid Stainless is committed to strict quality control and adheres to international standards, catering to industries like chemical processing, petrochemical, power generation, and food and beverage, where durability and corrosion resistance are crucial.
The AWS Class ER347 MIG and TIG fillers are austenitic stainless steel consumables primarily made up of iron, chromium (18–20%), nickel (9–11%), and niobium (columbium), which helps stabilize the alloy against carbide precipitation. This stabilization greatly enhances resistance to intergranular corrosion, especially after exposure to high temperatures, making ER347 perfect for heat-resisting applications. In terms of mechanical properties, weld metal created with ER347 filler typically boasts a tensile strength of around 75 ksi (515 MPa) along with good elongation and toughness, ensuring that the joints remain durable and crack-resistant during service.
