Electrodes - NI-99 Nickel

nickel-electrodes
  • Weldcote Metals NI-99 electrodes are designed for welding of gray iron castings to themselves as well as joining them to mild steels or stainless steels.
  • It is also used extensively to repair castings. The welds are quite machinable.
  • A preheat and interpass temperature of not less than 350 degrees Fahrenheit is recommended during welding. Nickel 99 is nominally 99% nickel electrode. Nickel 99 deposit welds are machinable, which is an important criterion when the casting is to be machined after welding.
  • Repairs with Nickel 99 are often single pass welding with high admixture. Even with high admixture, the weld deposit will remain machinable.
  • Nickel 99 works best on castings with low or medium phosphorus contents such as thin plates, machinery parts, frames and housings. Procedure: AC or DC reverse or straight polarity. Must have clean weld area. Bevel breaks and cracks deep enough so the first pass ties in the bottom of the crack. In most cases, preheating is not necessary, but heavy sections should be preheated to approximately 400 degrees Fahrenheit. Use a short arc and stringer beads are recommended. Skip or back-step weld and peen to relieve stresses. Allow the casting to cool slowly.
