NI-2

Electrode for high thermal impacts.

Alloy base

Ni, Cr, Mn, Fe, Nb

Special Features

  • Suitable for both joining and surface coating.
  • Excellent resistance to corrosion, oxidation and thermal shock.
  • Extra- ordinary Weldability without electrode overheating & strong tough welds.

    • Recommendation

    This is versatile electrode for all-position of nickel, intoned monel, nickel chromium-iron alloys, HK alloys stainless and heat resisting steels. Also nickel alloys to each other. Rotary kiln tyres. Heat treatment equipment such as retorts, rack, tays, tongs etc. Earth moving equipment, cryogenic equipment, joining dissimilar combinations of steels

    Procedure

    Clean the surface thoroughly so as to be free from rust, oil, grease, paint etc. Use reverse polarity only, maintain very short arc. Use stinger bead or slight weaving technique. Prepare edges so that the included angle or the "V" lies between 70-80° and root gap should be 2 mm. Dry the electrode prior to welding for approx. 300oC for 2 hours. The crater to be filled properly to avoid crater crack.
