| 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.. | ||||||||||||||||||||||||||||

| Electrode having a nickel-copper core wire for welding cast iron with preheating. Iron admixture from base metal should be kept low. Thus electrode is preferably used for making filler and cover passes or for filling-up shrinkage cavities.It is advisable to “butter” groove faces with ENI 402 electrode. Weld metal closely matches colour of base metal. Easy arc striking and restriking, stable arc. Weld metal is machinable. Weld shortbeads. Well-suited to welding cast iron with lamellar graphite, white, and black heart malleable cast iron, nodular cast iron. | ||||||||||||||||||||||||||||

| Basic coated electrode with Ni-Cr-Fe type nickel base deposit. Used for repairing and joining of nickel alloys, 5 – 9% Nickel steels, cryogenic stainless steels down to -196°C, Incoloy 800 and other high temperature steels. For joining dissimilar materials as stainless steels/low alloyed steels, stainless steels/Nickel alloys, buffering of difficult to weld steels. Weld metal deposit is insensitive to cracks, has very good resistance to acids, salts and alkaline solutions, molten salt (e.g. cyanide) in oxidizing and carburization atmospheres (avoid a sulphurous atmosphere). Generally used for welding on oven parts, burners, heat treatment equipment, cement works, moulds, transport and storage tanks of liquid gas. Chemical industries, petrochemical industries, glassworks, civil engineering, repairing and maintenance workshops. | ||||||||||||||||||||||||||||
