Електроди зварювальні Monolith НЖ-13 Плазма

AWS A5.4:E 318-15
EN ISO 3581-А-Е 19 12 3 Nb B 2 2
CONDITIONS OF USE
  • applied when welding in all spatial positions
  • welding is performed with a direct current of reverse polarity
  • welding is performed without further heat treatment with a short arc, the edges are cleaned before welding
SPECIAL PROPERTIES
  • ensures the production of weld metal resistant to intergranular corrosion during testing
  • surfacing coefficient: 0,18…0,21 g/A•min
  • consumption of electrodes per 1 kg of deposited metal: 1,3…1,4 кг
НЖ-13 Plasma electrodes are used for welding responsible structures of corrosion-resistant chromium-nickel-molybdenum steel grades 10Х17Н13М2Т, 10Х17Н13М3Т, 08Х21Н6М2Т, AISI316Ti, X2CrNiMoN225 and the like, operating at a temperature of +350°С, when the weld metal has strict requirements for stability against intercrystalline corrosion. Welds in all spatial positions except vertical from top to bottom, with direct current of reverse polarity
