AWS A5.15 ENi-C1/Z308 Cast Iron Welding Electrode

Description
Z308 is a covered welding electrode with pure nickel core and graphitic coating for cast iron. The Weld seam metal has excellent machinability and crack resistibility. Both AC and DC can be applied.. It can equivalent to: AWS A5.15 ENi-C1.

Applications
It is used for repairing welding thin pieces and processing surface of cast iron, as well as important grey cast iron pieces, such as engine gear box, machining tools, guideway, etc.

Attention
a.       welding electrodes must be baked for 1 hour at the temperature of 80-120ºC before welding.
b.       Hammering the welded seam to dispel stress around the welding region and to avoid cracking.
c.       Large current should be avoided in cold welding for cast iron, so as to reduce impurities of base metal to penetrate the weld seam and to reduce the width of the weld zone, and then to improve the ability of crack-resistance and capability of machine processing of the weld seam.
