AWS Class EB3 SAW & Flux Welding Wire – Composition, Properties, and Uses
AWS Class EB3 SAW & Flux can be defined as a flux-cored wire electrode that is used in tandem with submerged arc welding. The wire electrode is designed to facilitate the joining of low-alloyed steels without preheating treatment. The resulting weld is of high quality and can be used in various applications. This blog post aims to comprehensively analyze AWS Class EB3 SAW & Flux. We will discuss its composition, physical and mechanical properties, uses, heat treatment, and corrosion resistance.
What is AWS Class EB3 SAW & Flux?
AWS Class EB3 SAW & Flux Welding Electrodes are welding rods specifically designed for submerged arc welding (SAW). They are most commonly used in industrial, commercial and automotive applications. The electrodes feature an extruded coating comprising high iron and manganese oxide levels. This provides excellent arc stability and self-removal slag during the welding process. These rods also possess superior strength and remarkable longevity even when exposed to corrosion, cracking, or abrasion. Additionally, their consistent production results in exceptional deposition efficiency, reducing labour costs and cycle times while providing superior welds with outstanding mechanical properties.
EB3 SAW & Flux Welding Wire Composition
The primary components of AWS Class EB3 SAW & Flux welding wire include Fe, Mn, Si, C, Ni, Cr, Mo, and Ti. The wire’s flux comprises minerals such as calcium fluoride, aluminium oxide, and titanium dioxide. The flux’s primary function is to shield the molten weld pool from atmospheric contaminants and to prevent premature solidification.
