EutecTrode® Xuper NucleoTec 2222

Low heat input, high nickel based alloy manual electrode

Features and benefits

  • With proprietary formulation for maximum safety margin welding crack repairs on thick section parts of low alloy or air-hardenable steels.
  • Also developed for safe, reliable joints between ferrous & non-ferrous metals in dissimilar combinations eg. carbon / high alloy / stainless steels, various nickel & copper based alloys.
  • Reliable weld metallurgical properties retained from cryogenic to refractory temperatures
  • Unique plastic ductility properties minimise harmful residual stresses and distortion
  • Exceptional resistance to fatigue cracks caused by stress raisers or thermal cycles
  • Coefficient of thermal expansion similar to steel reduces welding stresses
  • Maximum resistance to hydrogen induced cold cracking defects
  • Highest dilution tolerance for Fe, Cr, Ni, Mn, C, Cu
  • Thermal shocks do not embrittle the weld deposit structure
  • Suitable for service in corrosive or high temperature environments
  • Economises costly preheating and Post Weld Heat Treatment procedures
