Product name:KNi-70B
 
Classification:A5.11 / ENiCrFe-2
 
 

  1. KNi-70B is designed for welding in DC.
  2. It provides good heat and corrosion resistance at high temperature (<980°C).
  3. It is ideal for welding Ni-Cr-Fe alloy, 9%Ni steel, forged/casting working pieces, and dissimilar materials (carbon steel, stainless steel, nickel or nickel-based alloy).

 

Welding Instruction

  1. Clean the surface of the base metal before welding.
  2. It is difficult for welding in V & O-H positions, so F welding is recommended.
  3. Baking temperature should be between 350~400°C during 30~60 minutes before welding. No PWHT is required for base metal.
  4. To avoid weave arc, make a short arc in low current.
