AWS A5.5: E7018 A1

Description

Premium low-alloy, high-tensile, iron-powder type electrode designed for structural applications requiring high strength and crack resistance. Suitable for high-strength steels (up to 550–600 MPa) and low-temperature service. Produces smooth, uniform weld beads with excellent slag detachability. Operates on AC and DC+ polarity. Ideal for bridges, heavy structures, pressure vessels, pipelines, and general fabrication.
