Електроди зварювальні Моноліт ЦЧ-4

ISO 1071: E C Z Fe2
ГОСТ 9466 ЦЧ-4
CONDITIONS OF USE
  • the welding process should be carried out only on clean, non-oily and non-rusty surfaces (before welding, the joint should be polished)
  • welding is performed with short rollers 25...35 mm long with cooling of each roller in air to 60 °С and by forging each part of the seam with light blows of a hammer
  • when welding ductile and high-strength cast iron, the length of the roller can be increased to 80...100 mm
  • at a high voltage of the idle speed of the transformer, not less than 50 V and short lengths of welding cables allow AC welding.
SPECIAL PROPERTIES
  • electrodes are characterized by good welding and technological properties, namely: easy ignition and stable burning of the arc, small losses of metal from spattering, good formation of the weld metal when welding in the lower position
  • in the weld metal, welded with these electrodes, a strong carbide former - vanadium is introduced, the formed carbides of this element do not dissolve in iron, but have the form of finely dispersed non-solid inclusions, while the metal base turns out to be decarburized and quite plastic
  • surfacing coefficient: 0.15... 0.20 g/A•min
  • consumption of electrodes per 1 kg of deposited metal: 1.4...1.6 kg
Electrodes ЦЧ-4 are intended for cold welding of structures made of high-strength cast iron with nodular graphite and gray cast iron with lamellar graphite, as well as their connection with steel. Electrodes can be used to weld damaged parts and welding defects in high-strength and gray cast iron castings and preliminary surfacing of the first one or two layers on worn cast-iron parts for subsequent surfacing with special electrodes
