Електроди зварювальні Monolith ЭА-395/9

AWS A5.4: E308L-16
EN ISO 3581-A-Е Z 20 25 5 Cu N L В 2 2
CONDITIONS OF USE
  • applied when welding in all spatial positions, except from top to bottom, with a constant current of reverse polarity
  • welding must be performed with a short arc, without transverse oscillations, the edges should be cleaned before welding
SPECIAL PROPERTIES
  • very high reserve of austenity (EA-3)
  • excellent mechanical properties of the deposited metal
  • high welding and technological properties, easy separation of the slag crust, and the formation of a seam with a smooth transition to the base metal
  • surfacing coefficient: 0.19...0.20 g/A•min
  • consumption of electrodes per 1 kg of deposited metal: 1.4...1.5 kg
EA-395/9 electrodes are designed for responsible welding structures made of alloyed steels of increased and high strength, heat-resistant and low-magnetic steels, steels of the type AK 23, AK 25, AK 27, as well as welding dissimilar steels.
