AWS Class ER347 SAW and Flux are top-notch welding materials crafted for joining austenitic stainless steels that need exceptional resistance to intergranular corrosion and stress corrosion cracking. These consumables are specially designed for Submerged Arc Welding (SAW) applications, ensuring smooth, defect-free welds with great penetration and consistent mechanical properties. When you use ER347 SAW wire alongside compatible flux, you get strong, durable, and reliable joints, making them perfect for critical applications in industries like chemical, petrochemical, and food processing.
The makeup of AWS Class ER347 SAW wire and flux features iron, chromium, nickel, and niobium, along with trace amounts of carbon and other elements. Chromium and nickel boost corrosion resistance and toughness, while niobium helps stabilize the weld, preventing carbide precipitation and minimizing the risk of intergranular corrosion. The flux is designed to facilitate smooth arc transfer, promote slag formation, and create an optimal weld bead profile, all while shielding the molten weld pool from atmospheric contamination. Together, the wire and flux provide outstanding mechanical strength, ductility, and long-lasting durability.
