13 Sep FAQ: What are Cor-Match™ 80-CW and 810-W?
Welding electrodes are lengths of wire that are connected with your welding machine to create an electric arc. Current passes through this wire to produce an arc, which generates a heat to melt and fuse metal for welding. Central Steel Service added Cor-Match™ products to complement its high-quality supply line of high-strength and high-strength weathering steels. Cor-Match™ 80-CW and 810-W are low-alloy steel electrodes designed for welding on corten and weathering steels. They provide excellent mechanical properties and a close color match to weathering steels.
Interested in learning more about Cor-Match™ 80-CW and 810-W? Check out the answers to these frequently asked questions below.
What types of weathering steels are suitable for welding with Cor-Match™ products?
Cor-Match™ 80-CW and 810-W are recommended for single and multiple pass welding of self-weathering steels per ASTM A588, A606-4, A242, A709-50W, and A847, where color match and corrosion resistance are required.
What makes Cor-Match™ 80-CW unique for weathering steel welding?
Cor-Match™ 80-CW is a composite, metal-cored electrode designed for flat and horizontal welding of weathering steels. It offers a nearly non-existent spatter emission, thanks to its pure spray transfer using 75-80% argon and carbon dioxide.
What is the difference between metal cored and solid cored welding wire?
Metal-cored and solid-cored welding wires differ in composition, deposition rate, and application:
Composition:
- Solid wires are single-material.
- Metal-cored wires have a core with various metals.
Deposition Rate:
- Solid wires have lower deposition rates.
- Metal-cored wires offer higher deposition rates.
Application:
- Solid wires are versatile.
- Metal-cored wires are for high-deposition-rate tasks.
- Choose based on material and productivity needs.
What are the advantages of Cor-Match™ 810-W for weathering steel welding?
Cor-Match™ 810-W is a gas-shielded, flux-cored electrode suitable for all position welding of weathering steels. It provides excellent welder appeal with a spray transfer, thin slag that removes easily, and a smooth bead profile.
Can I use Cor-Match™ 8018-W for stick electrode welding on corten and weathering steels?
Yes, Cor-Match™ 8018-W is recommended for stick electrode welding on corten and weathering steels. It offers excellent mechanical properties and a close color match.
What are the typical mechanical properties of Cor-Match™ 80-CW and 810-W?
Cor-Match™ 80-CW (75% Ar/25% CO2):
- Ultimate Tensile Strength: 92,000 psi
- Yield Strength: 78,100 psi
- Percent Elongation: 24.7%
- CVN (ft lb f) @ -20F: 43
Cor-Match™ 810-W (75% Ar/25% CO2 and CO2):
- Ultimate Tensile Strength: 91,300 psi and 86,500 psi
- Yield Strength: 78,800 psi and 71,200 psi
- Percent Elongation: 24% and 25%

What are the recommended welding parameters for Cor-Match™ 80-CW and 810-W?
You can find the recommended welding parameters for various electrode diameters and shielding gases here.
What are the characteristics of Cor-Match™ 80-CW?
Cor-Match™ 80-CW offers better penetrating characteristics compared to solid electrodes, eliminating cold lap or lack of fusion. It generates less fume than flux-cored electrodes, making it useful in scenarios where slag removal and cleanup are problematic. Additionally, it allows for faster travel speeds, increasing productivity.
What are the applications of Cor-Match™ 810-W?
Cor-Match™ 810-W is suitable for all position welding and matches the coloring and corrosion resistance of weathering steels. It is used in various structural components in steel fabrication projects, including bridge construction, transmission pole fabrication, and building facades.
How do Cor-Match™ 80-CW and Cor-Match™ 810-W achieve a color match and corrosion resistance with self-weathering steels?
These products contain alloy additions that match the alloys in self-weathering steels, resulting in weld metal that matches the corrosion resistance and the orange/brown patina color of self-weathering steels used in unpainted applications.
