Cored wire

Cored wire is a type of wire electrode used in arc welding, featuring a hollow core filled with flux or alloying powder. The core materials support arc stability, slag formation, deoxidation, or gas shielding, depending on the application. Cored wires offer several advantages over solid wires, especially in high-deposition and industrial welding.

Types of cored wire:

• Gas-shielded cored wire (FCAW-G): requires external shielding gas, such as CO₂ or argon mixtures.
• Self-shielded cored wire (FCAW-S): forms its own shielding atmosphere through the core ingredients – ideal for outdoor or mobile welding.

Advantages:

• Higher deposition rates at the same current
• Improved gap-bridging capabilities
• Reduced spatter (depending on type)
• Suitable for automation and heavy-duty welding

Typical applications:

Cored wires are commonly used in steel construction, shipbuilding, maintenance welding, and pipeline fabrication, where strong, reliable welds and high productivity are essential.
