Welding electrodes Monolith NiCu-B

AWS A5.15: ENiCu-B
EN ISO 1071: E C NiCu 1
Terms of use
  • welding is continued after cooling the welding place in air to a temperature not higher than 60°C (140°F); 
  • use for repair welding only.
Special properties
  • obtaining of deposited metal with high processability, as well as corrosion-resistant features in aggressive liquids and hot gases;
  • metal deposited with the help of these electrodes, due to the low hardness of the last layers, is easily cut or abrasively processed;
  • melting temperature of this alloy is similar to the melting temperature of cast iron, therefore, during the welding process, the alloy is well mixed with
    cast iron;
  • nickel and copper in the alloy contribute to the graphitization of cast iron in the alloy zone, i.e. reduce the risk of a significant bleaching zone formation;
  • since the alloy has good plastic properties, the weld metal is resistant to cracking.
NiCu-B electrodes are used for welding without heating or with slight heating with short joints of 20 - 30 (0.7 - 1.1) mm (in) long, welding of casting defects and surfacing of parts made of gray, high-strength and malleable cast iron. Most suitable for welding of the first layer in joints requiring high density, as well as for welding of joints requiring increased surface cleanliness after mechanical processing. After applying each seam, the welded area is hammered with light blows of a hammer.
