Електроди зварювальні Monolith НР-70 Плазма

EN 14700: E Z Fe1
CONDITIONS OF USE
  • before surfacing, it is necessary to clean the welded part of dirt, rust, oil
  • it is not recommended (in order to avoid cracking) to weld steel parts in more than two layers, cast iron parts - in one layer
  • in case of heavy wear of the part, the lower layers should be welded with other electrodes, the choice of which depends on the composition of the base metal
  • for carbon low-alloyed steels, the previous layer can be welded with Monolith RC, АНО-36 electrodes, for manganese-alloyed steels - with UONI 13/55 Plasma electrodes
SPECIAL PROPERTIES
  • the metal deposited by the electrodes has good wear resistance and satisfactory impact resistance
  • the stability of the properties is achieved by observing constant deposition conditions
  • surfacing coefficient: 0,15…0,16 g/A•min
  • consumption of electrodes per 1 kg of deposited metal: 1,5…1,6 kg
HP-70 Plasma electrodes are designed for welding parts that work under conditions of intense impact load and friction metal on metal (wearing of railway crossings, ends of rails, auto clutch, axles, shafts).
