Wethering Steel

JACKSUN ULTRA 7018 W

AWS: E7018 W1

JACKSUN ULTRA 7018 W is a low-hydrogen, rutile-coated electrode designed specifically for welding weathering (COR-TEN) steels.
It provides excellent corrosion resistance by forming a protective patina on the weld, matching the base material properties.
Ideal for bridges, towers, silos, and structural steel exposed to atmospheric corrosion.
