Application/properties: electrode for producing crack-free and tough welding joints, also suited for welding steels having a carbon content of up to 0.6%. The weld metal has very low hydrogen content and is resistant to ageing. Approved for rail joint welding; Good gap bridging properties. the electrode has a stable and concentrated arc is therefore well suited for positional welding. Welds are if X-ray quality. CTOD-tested for offshore application.
