LY-Z208 is a graphitic type coating cast iron electrode with carbon steel core. Both AC and DC can be applied in welding.Weld seam metal has excellent crack resistibility.And its price is cheaper.


It is used for repairing welding defects of gray cast iron .

a.Welding electrodes must be baked for 1 hour at the temperature of 150℃ before welding.
b.For cast iron parts bearing impact stress ,it is not good to use it .
c.For welding detects of small and thin cast iron parts fabricated by low steel,welding electrodes needn’t be preheated;for general welded pieces,welding electrodes should be preheated to around 400℃, cool it after welding and the welding zone may be processed by cutting.
