ACCORD WITH: GB/T 10044 EZNi-1

EQUIVALENT NORM: AWS A5.15 ENi-C1

DESCRIPTION:

·GSE.Ni-C1 is a covered welding electrode with pure nicklel core and graphitic coating for cast iron .The weld seam metal has excellent machinability and crack resistibility .Both AC and DC can be applied.

APPLICATIONS:

·It is used for repair welding thin pieces and processing surface of cast iron,as well as important gray 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 80-120℃ 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.
