Description

AWS A5.23: ECNi1Submerged Arc Cored Wires Low-Alloy Steel,China, Tianjin

Category

AWS A5.23: ECNi1 is a low-alloy composite metal-cored wire electrode for submerged arc welding in high strength applications.  it meets AWS A5.23 chemistry Ni1, and is designed for tensile strength levels above 70 ksi.

FEATURES&BENEFITS

Not recommended

Industries

Structural & bridge fabrication, heavy equipment, Offshore

RECOMMENDED FLUXES

• 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

• Nominal 1% nickel weld deposit

• Weld deposit chemical composition requirements are identical to those for an ENi1-Ni1 solid wire/flux combination

• Provides excellent low-temperature toughness without excessive tensile strength

• 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.

• Provides atmospheric corrosion resistance to welds made on bare, unpainted weathering steels

• A higher-productivity alternative in virtually all applications currently using ENi1 solid wire

• Suitable for welding a range of non-alloyed steels in low-temperature of critical service requirements

TYPICAL OPERATING PARAMETERS*

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.
