Wethering Steel

JACKSUN ULTRA 8018 W

AWS: E8018 W2

JACKSUN ULTRA 8018 W is a low-hydrogen electrode designed for welding weathering (COR-TEN) steels.
It provides excellent corrosion resistance with a protective patina on the weld metal, ensuring compatibility with weathering steel structures.
Ideal for bridges, towers, silos, and structural steel exposed to atmospheric corrosion.
