COATED ELECTRODES
UNIVERSAL BASIC (7018)
Universal basic electrode for welding highly stressed steel assemblies (carbon
and carbon manganese) (tensile strength up to 560 MPa). It is characterized by
excellent mechanical properties, especially at low temperatures.
Application
• Piping,
• Pressure tanks,
• Shipyards,
• Offshore platforms,
• Quality steel constructions.
Products
• Excellent mechanical properties.
• Very low hydrogen content.
