EL KADESIA E 7018-1H4
Description

Basic coated engineered electrode for high-quality welds. Exceptional strength and toughness properties down to – 50 º C, Deposition efficiency about 110 %. Good welding in all position except for vertical-down, Very low Hydrogen content in the weld metal (under AWS container HD ≤ 4 ml/100g). The electrode is suitable for joint welding in steel, boiler, container, vehicle, ship and machine construction, and as well as a buffer layer for build-up welds with high-carbon steels. Suitable for welding steels of low purity and high carbon content. Particularly suitable for offshore constructions. CTOD-tested at -10 º C.
