Characteristics and Application
Pure nickel cast iron electrode AWS A515 ENi-Cl 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: it 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.
Typical chemical Composition of Weld Metal (%)
Welding Positions:
Notes on usage:
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.
