CATEGORY:

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

Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical depending on the type and thickness of steel being welded. Parameters are provided for informational purposes only. All values are approximate. The optimal voltage may vary (typically ±2 volts) depending on the choice of flux, material thickness, joint design, and other variables specific to the application. Likewise, actual deposition rate may vary depending on choice of flux and contact tip to work distance.
