CIN-2
For Repairing of Cast Iron
|
Class of: AWS A5.15 ENiFe-CI
JIS Z 3252 DFCNiFe

DESCRIPTION
CIN-2 is a high
grade special purpose electrode with ferro-nickel alloy core (45% Fe – 55% Ni).
This electrode is especially intended for cold welding of cast iron. Due to the
special character of the coatings, welding can be completed by lower current
compared with the conventional electrodes. So, the weld metal can be machined by
cutting tools and is not sensitive to cracking. As the weld metal has excellent
mechanical properties, it is most suitable for cold welding of ductile cast iron
(nodular cast iron).
APPLICATIONS
For welding of
nodular cast iron, repairing and joining all kinds of cast iron, such as
casings, machine frames, engine blocks, cylinders and valves. Also suitable for
underlay of hardsurfacing.
INSTRUCTIONS
1. Dry the electrodes at 80° ~ 110°C for 30 ~ 60 minutes before use.
2. Choose the welding current within the suitable welding current range.
3. As a rule, no preheating or postheating
is necessary, but the best result is obtained when base metal is heated to 100°
~ 200°C before welding.
