CIN-2For Repairing of Cast Iron

Class of: AWS A5.15 ENiFe-CIJIS Z 3252 DFCNiFe

DESCRIPTIONCIN-2 is a high grade special purpose electrode with ferro-nickel alloy core (45% Fe – 55% Ni). Thiselectrode 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 metalcan be machined by cutting tools and is not sensitive to cracking. As the weld metal has excellentmechanical properties, it is most suitable for cold welding of ductile cast iron (nodular cast iron).

APPLICATIONSFor welding of nodular cast iron, repairing and joining all kinds of cast iron, such as casings, machineframes, engine blocks, cylinders and valves. Also suitable for underlay of hardsurfacing.

INSTRUCTIONS1. 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 isheated to 100° ~ 200°C before welding.
