SUPER Ni
Description and application:
Electrode with pure Ni-core wire for cold welding of grey and malleable cast iron also suitable for joining them
with steel. Suitable for repair purposes, repair of broken parts, building up missing parts and correction of
machining errors, joining cast iron for rectification of castings. The weld material is soft and easy machinable
We suggest cold impact forging to achieve stress relieving.
By using small electrode diameters heat input should be kept low. Ground material should be clean. For scoring
we suggest our electrode Sekator 2 B or Sekator 2 A, grinding is not recommended.
Base materials:
Grey cast iron
Malleable cast iron
