AWS Class EB6 SAW & Flux Welding Wire – Composition, Properties, and Uses
AWS Class EB6 SAW & Flux is a welding wire of nickel-iron alloy, typically used for welding dissimilar metals. This welding wire is designed to provide high strength and flexibility, making it ideal for heavy-duty welding applications. This blog post will explore the composition, physical and mechanical properties, uses, heat treatment, and corrosion resistance of AWS Class EB6 SAW & Flux.
What is AWS Class EB6 SAW & Flux?
AWS Class EB6 SAW & Flux electrodes are flux-cored arc welding (FCAW) electrodes with superior strength and flexibility. These wires produce excellent welds even for difficult-to-weld metals, such as cast iron alloys, stainless steels, and other high alloy materials. When used with self-shielding or gas-shielded FCAW processes, they can produce excellent bead appearance on vertical down and overhead welding positions. The produced beads have high shear and tensile strengths while providing maximum joint integrity. Even under fluctuating conditions, they offer superior mechanical properties while ensuring consistent weld quality at a low cost per pound of weld metal deposited. With their unique characteristics, Class EB6 SAW & Flux electrodes enable efficient production in structural steel fabrication and repair industries.
