AWS A5.23: ECF3 Submerged Arc Cored Wires Low-Alloy Steel
DESCRIPTION:
AWS A5.23: ECF3 is a low-alloy composite metal-cored wire electrode for submerged arc welding in high strength applications. And it meets AWS A5.23 chemistry F3, and is designed for tensile strength levels above 100 ksi.
FEATURES&BENEFITS:
Metal-cored wire can offer improved deposition rates compared to solid wires at comparable amperages
Metal-cored wires offer broader penetration profiles compared to solid wires at comparable welding parameters
Weld deposit chemical composition requirements are identical to those of EF3 solid wires
Weld deposit chemical composition consists of less than 1% nickel
Very good low-temperature impact toughness in both the as-welded and stress-relieved conditions
Provides potential to increase travel speed for improved productivity
Helps to prevent burn-through when welding at high currents on root passes and relatively thin materials.
Suitable as a higher-productivity alternative in many applications currently using EF3 solid wire
Suitable for use in sour gas applications where stress corrosion cracking due to hydrogen-sulfide is a concern
Helps minimize the risk of cracking in critical applications and harsh service environments
