Z208

Z208 Cast Iron Welding Electrode
Accord with:GB/T 10044 EZC

Description:
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.

Applications:
It is used for repairing welding defects for gray cast iron.

Chemical Composition of Deposited Metal: (%)

Standard	2.00-4.00	≤0.75	2.50-6.50	≤0.10	≤0.15	The rest
Typical	2.70	0.40	4.20	0.006	0.020

Recommended Current (AC or DC) 

Size(mm)	2.5*300	3.2*350	4.0*400	5.0*400
Current(A)	60-90	90-120	150-180	190-220

Attention:
a.       welding electrodes must be baked for 1 hour at the temperature of 150ºC 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 need not be preheated. For general welding pipes, welding electrodes should be preheated to around 400ºC, cool it after welding and the welding zone may be processed by cutting.

Z308

Z308 Cast Iron Welding Electrode
Accord with:GB/T 10044 EZNi-1
Equivalent norm: AWS A5.15 ENi-C1

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.

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.

Z408

Z408 Cast Iron Welding Electrode
Accord with:GB/T 10044 EZNiFe-1
Equivalent norm: AWS A5.15 ENiFe-C1

Description:
Z408 is a graphitic (with strong reducing) type coating with Ni/Fe core welding electrodes for cast iron. It has features as follows: high toughness, excellent plasticity, low linear expansion coefficient, etc. Both AC and DC can be applied with welding.

Applications:
It is used for repairing welding important and high toughness parts made of cast iron and modular iron, such as cylinder head, motor stand, gear wheel, etc.

Attention:
a.       welding electrodes must be baked for 1 hour at the temperature of 150ºC before welding.
b.       Small current is the best to be adopted.

Z508

Z508 Cast Iron Welding Electrode
Accord with:GB/T 10044 EZNiCu-1
Equivalent norm: AWS A5.15 ENiCu-B

Description:

Z508 is a graphitic (with strong reducing) type coating with Cu-Ni alloy (Monel) core welding electrodes for cast iron. Its technology properties and machinabilities are both close to those of Z308 and it is not suitable for welding pressed position, but suitable for welding gray cast iron.

Applications:
It is used for repairing welding gray iron casting strength of which is not so highly required.

Chemical Composition of Deposited Metal: (%)

	C	Mn	Si	S	Ni	Fe	Cu
Standard	0.35-0.55	≤2.30	≤0.75	≤0.025	60-70	3.0-6.0	23-35

Recommended Current (AC or DC)

Size(mm)	3.2*350	4.0*400	5.0*400
Current(A)	90-110	120-150	160-190

Attention:
a.       welding electrodes must be baked for 1 hour at the temperature of 150ºC before welding.
b.       When welding, narrow weld seam is recommended and its length should be less than 50mm, and after welding, hammer the weld metal immediately to dispel stress around the welding region and avoid cracking.
