AWS A515 ENiFe-Cl

Characteristics and Application
Pure nickel cast iron electrode AWS A515 ENiFe-Cl is suitable for the weldingof high-strength gray iron and nodular cast iron, such as cylinder, engine block, gear box, etc.. Characteristics:it 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 cutting performance is lower than THZ308 and THZ508 slightly. THZ408 is used in the welding of gray iron and nodular cast iron for room.

Notes on usage:
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.
