The weld is machinable. It is recommended to use the finest possible electrode and a weak welding current.
The ferronickel bimetallic core (lower electrical resistance) ensures higher welding speeds and high melting efficiencies and the risk of overheating the cast iron is lower.
Therefore, the entire length of the electrode can be used.
Suitable for welding all gray cast iron and connecting cast iron to steel,
especially for spheroidal graphite cast iron (ductile iron).
The weld metal is very similar in color to the base material and the corrosion is also identical to the base material.
Even clean weld material is workable.
Welding: Before sanding, completely clean the welding area of oil, scaling, etc. dirt.
When welding cast iron, the heat input must be as low as possible (low current welding).
The suture must not be wider than twice the diameter of the electrode core and no more than ten times the diameter of the electrode core.
Preheating to 300 oC and slow cooling is recommended.
To achieve good throughput and smooth flow of weld metal, it is recommended to weld with counter-polar direct current (DC +).
The best crack resistance is obtained by AC welding. The constant change in polarity ensures a smooth, smooth seam,
which is important for hard-welded casting
The sealed package is stable indefinitely at a temperature between 10 and 40 degrees and a relative humidity of less than 80%.
