spot welding electrodes electrodeTHZ408 welding electrode 6013 weld wire AWS ENiFe-CI

APPLICATIONS:

It is suitable for the welding of high-strength gray iron and nodular cast iron, such as cylinder, engine block, gear box,etc..

CHARACTERISTICS:

THZ408 is the cast iron electrode with nickel iron alloy core and strong reduction of graphite coating . It can be used in AC and DC dual purpose, has stable arc,and is easy to operate. The electrode has the characteristics of high strength, good plasticity, low linear expansion coefficient and so on. The crack resistance for grey cast iron is as much as that for THZ308, while the crack resistance for nodular cast iron is more than THZ308. For cast iron with higher phosphorus (0.2%P), it also has a good results and its tocutting performance is lower than THZ308 and  THZ508 slightly. THZ408 is used in the welding of gray iron and nodular cast iron for room

ATTENTION:

1 Before welding, the electrodes need to be baked for 1 hour with the temperature of 150±10℃ before using.

2 Use small current for welding as far as possible.

3 It can eliminate the welding stress and avoid the crack by the hammer.

THZ208

 Steel Cored Gray Cast Iron Electrode  GB/T 10044 EZC  DFCC1 JIS

Application: welding up the defects of gray iron castings.

Features: THZ208 is the cast iron electrode with a low-carbon steel core and strong graphite type coating. It can be used in AC and DC dual purpose and has a low price. The welding seam can be changed into gray cast iron when it is cold slowly. But it has a poor anti cracking performance.

Precautions:

1 Before welding, the electrodes need to be baked for 1 hour with the temperature of 150±10℃ before using.

2 The defects in small thin-wall castings with little stiffness may not be preheated weld repairs, while the general welding should be  preheated to 400±10℃, kept welding heat preservation, and slow cooling, then the welding repair may be able to carry out cutting processing.

3 This electrodeb should not used to important casting structures that withstand stresses and shocks.

THZ308

APPLICATIONS:

It is suitable for the welding of thin pieces of cast iron welding and machining surfaces, such as cylinder heads, important gray cast iron engine blocks, gear boxes, and Machine Tool and so on.

CHARACTERISTICS:

THZ308 is pure nickel welding core, strong reduction of graphite type coating iron rod. It can be used in AC and DC dual purpose and is  easy to operate. When welding, it is not necessary for weldment to preheat. It has good crack resistance and processability.

ATTENTION:

1 Before welding, the electrodes need to be baked for 1 hour with the temperature of 150±10℃ before using.

2 It can eliminate welding stress and avoid crack by hammering the welding seam.

3. In order to reduce the impurity elements in the base metal penetration weld, narrow white band width, improve crack resistance and processing properties, it should use small current welding in cast iron cold welding.
