Description:
AWS ENi-C1 is a covered welding electrodes with pure nickel core and graphitic coating for cast iron . The weld seam metal has excellent machinability and crack resistibility.It is a graphite type electrode with pure nickel core. Suitable for repairing of welding various cast irons. The weld metal zone has a few inclination to harden, then machining is easy. But the colour can not match the base metal.

APPLICATIONS:
Used for repair welding on thin cast iron pieces and machined surfaces, such as some key gray cast iron pieces like engine bearers, guide rails of machine tools, pinion stands, etc. 

Matters need attention:
1. By hammering  welding line to eliminate the ability of welding area for avoiding crack
2. Cold welding of cast iron welding should avoid the use of a high-current welding, to reduce the impurity elements  infiltrate in the welding line of base metals , narrowing the width of the white area to improve the capacity of the crack resistance and machining
3. Welding electrodes must be baked about 1 hour under 80-120 degrees
