Cor-Match® – The Weathering Steel Wire & Electrode
For welding on Corten and weathering steels, Central Steel Service recommends our Cor-Match® products, which feature excellent mechanical properties and a close color match to weathering steels.
Cor-Match® 80-CW and 810-W are low-alloy steel electrodes 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.
Cor-Match® 80-CW is a composite, metal-cored electrode for FLAT AND HORIZONTAL welding of weathering steels. 80-CW welds in a pure spray transfer, using 75-80% argon-balance carbon dioxide resulting in a spatter emission that is nearly non-existent.
Cor-Match® 810-W is a gas-shielded, flux cored electrode for ALL POSITION welding of weathering steels. Welder appeal is excellent with a spray transfer, thin slag, which removes easily and cleanly. Plus, it provides a smooth bead profile.
**For stick electrode welding on Corten and weathering steels, Central Steel Service recommends Cor-Match® 8018W, which features excellent mechanical properties and a close color match.

Cor-Match® 80-CW: Penetrating characteristics of this tubular electrode are better than solid electrodes, eliminating “cold-lap” or lack of fusion, on heavier plate or scaled areas. Cor-Match® 80-CW generates less fume than flux-cored electrodes and is useful where slag removal and cleanup present problems. Faster travel speeds are achievable with solid electrodes, which increases productivity. Modern proprietary manufacturing technology ensures the highest levels of quality, consistency and welding performance in our industry.
- Matches coloring and corrosion resistance of weathering steels
- All position welding capability
- Good mechanical properties
Cor-Match® 80-CW and Cor-Match® 810-W contain alloy additions, which match the alloys contained in self-weathering steels. This provides weld metal, which matches the corrosion resistance and the orange/brown patina color of self-weathering steels used in unpainted applications, such as bridge construction, transmission pole fabrications, building facades and other structural components used in a variety of steel fabrication projects.
