When working with weathering steels like ASTM A588 or A606-4, A847M A709-50W selecting the appropriate welding consumable is crucial. Enter the Cor-Match™ 80-CW wire, a metal-cored welding wire engineered for these specific materials.

What is a Cor-Match™ 80-CW Wire?

Cor-Match™ 80-CW is a composite, metal-cored wire tailored for horizontal and flat welding of weathering steels. It operates in a pure spray transfer mode using a shielding gas mixture of 75-80% argon balanced with carbon dioxide, resulting in minimal spatter.

 Key Cor-Match™ 80-CW Features

A Cor-Match™ 80-CW wire delivers efficiency, precision, and long-term durability. From deeper weld penetration to a cleaner work environment, this welding wire brings multiple advantages to structural and aesthetic applications alike. 

Its tubular design offers superior penetration compared to solid wire, reducing the risk of lack of fusion on thicker or scaled materials. The wire also generates less fume than flux-cored wires, simplifying slag removal and cleanup

Mechanical Properties That Deliver Performance

Strength and durability are non-negotiable when welding structural steel, especially for exposed applications. A Cor-Match™ 80-CW wire delivers reliable mechanical properties that match the base metal’s strength while maintaining flexibility and impact resistance.

• Tensile Strength: Approximately 92,000 psi
• Yield Strength: Around 78,100 psi​
• Elongation: Approximately 24.7%​
• Charpy V-Notch Toughness: 43 ft-lbf at -20°F ​

Cor-Match™ 80-CW Welding Parameters

Dialing in the right settings is crucial for achieving optimal weld performance. A Cor-Match™ 80-CW wire offers flexibility across various diameters, amperages, and voltages, allowing welders to fine-tune their approach based on project needs.

• Diameter: Available in .035″, .045″, .052″, and 1/16″, giving welders a range of options to suit different material thicknesses and applications.
• Amperage: Operates between 160 to 520 amps, with variations depending on the selected wire diameter and welding position.
• Voltage: Best performance is achieved between 24 to 37 volts, ensuring proper arc stability and weld penetration.
• Contact Tip to Work Distance (CTWD): Typically set between 1/2″ to 1-1/4″, providing the ideal arc length for maintaining control and consistency during the weld.

Cor-Match™ 80-CW Applications

A Cor-Match™ 80-CW welding wire is ideal for welding self-weathering steels used in unpainted applications such as bridges, transmission poles, building facades, and various structural components. The weld metal matches the corrosion resistance and develops a patina similar to the base material, ensuring aesthetic consistency. 

For projects involving weathering steels, Cor-Match™ 80-CW offers a reliable solution, providing excellent mechanical properties and a close color match to the base material. Its design ensures efficient welding with minimal cleanup, making it a valuable addition to your welding consumables.
