E7018-1
AWS A5.1 E7018-1, E7018
7018-1 is general low hydrogen mild steel all position electrodes recommended for mild –high carbon base metals, ship building/barge offshore drilling rigspower, petrochemical and boiler plants. These rods are formulated to have quality welds with very easy slag removal orself-peeling, excellent welder appeal on those poor weldable steels. 7018-1 is easy to control which is used often for high impact levelat -50°F while providing a stable arc with a flat to slightly convex fine ripple weld appearance.
