Electrode having a pure nickel core wire, designed for the welding of cast iron with preheat. Suitable for welding grey cast iron, white and grey mallable cast iron, nodular cast iron. For reparing cracked an worn castings or joining cast iron parts to components made of steel, copper and nickel materials. Provides easy arc striking, restriking and stable arc. Weld metal is machinable. Weld short beads (approx. 30 to 50 mm long). For reducing weld residual stresses, hammer peen welds before cooling. Preferably used with DCEP but possible to use also with AC.
Electrode having a pure nickel core wire for welding cast iron without or with low preheating (max. 300°C). Suitable for welding cast iron with lamellar graphite, white and black heart malleable and nodular cast iron. Used also for repair welding of cracked cast iron parts or joining components made of steel, copper or nickel materials to cast irons. Weld metal is machinable. Provides easy arc striking and restriking, stable arc and smooth bead surface. Weld short beads, about 30 to 50 mm long. In order to reduce weld residual stresses, hammer-peen welds slightly before cooling. Preferably used with DCEP but possible to use also with AC.
Electrode having a nickel-copper core wire for welding cast iron with preheating. Iron admixture from base metal should be kept low. Well-suited to welding cast iron with lamellar graphite, white, and black heart malleable cast iron, nodular cast iron. Weld metal closely matches colour of base metal. Thus electrode is preferably used for making filler and cover passes or for filling-up shrinkage cavities. Provides easy arc striking and restriking and stable arc. Weld metal is machinable. Weld short beads, about 30 to 50 mm long. In order to reduce weld residual stresses, hammer-peen welds slightly before cooling.

Electrode having a nickel core wire, for welding on grey cast iron with and without preheating. Suitable for welding joints as well as for surfacing of worn cast iron parts. Suitable to use in repair of machine frames, machine housings, machine parts and bearing blocks. The electrode has a very soft, regular fusion, and a quiet and steady arc. It is well suited for positional welding. Very little dilution with the parent metal takes place, resulting in good machinability of the transition area. Weld short beads, about 30 to 50 mm long. In order to reduce weld residual stresses, hammer-peen welds slightly before cooling. Preferably is used with DCEN but possible to use with also AC.
Electrode having a nickel-iron core wire, for welding cast iron with or without preheating. The weld metal features a low coefficient of thermal expansion and as a result, little shrinkage. It has higher strength properties than pure nickel weld metal and is therefore preferably used for welding nodular cast iron, white and black heart malleable cast iron, as well as austenitic nodular cast iron or joining these metals to components made of steel, copper or nickel materials. Easy arc striking and restriking, stable arc, smooth bead. Weld metal is machinable. Weld short beads.
