EL KADESIA I E7018

EL KADESIA I E7018
Description

Basic coated engineered electrode for high-quality welds. Excellent strength and toughness properties down to – 50 º C, Metal recovery approx.; 110 %. Good weldability in all position except for vertical-down, Very low Hydrogen content. Suitable for welding steels with low purity and high carbon content. Welding in steel construction, boilers and tanks manufacture, vehicle construction, shipbuilding, and machine construction as well as for buffer layers on build ups on high carbon steels. Especially suitable for off-shore construction, it can be used in severe gaseous media applications.
