Applications and Properties:<\/strong><\/strong><\/p>\n\n\n\n

Basic electrode that uses nano technology in a humid environment with 80% humidity, the electrode coating is resistant to moisture absorption for 9 hours. This electrode is suitable for producing crack-free and tough welding joints and also 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. Because of its double covering (up to 3.25 mm), 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.<\/p>\n\n\n\n
