Електроди зварювальні Моноліт ЦУ-5

AWS A5.1: E7016
EN ISO 2560-A-E 42 A B 2 2
CONDITIONS OF USE
  • welding should be carried out with a direct current of reverse polarity, (+) on the electrode, without preheating and subsequent heat treatment only on a short length of the arc along the cleaned edges
SPECIAL PROPERTIES
  • provide high resistance of the weld metal to the formation of pores during arc extension, allow welding of the root seam of thick-walled pipes with a large gap
  • perform welding with a short arc, cleaning the edges before welding
  • surfacing coefficient: 0,13…0,16 g/A•min
  • consumption of electrodes per 1 kg of deposited metal: 1,4…1,5 кг
For welding elements of heating surfaces of boiler units, a also root layers of seams, joints of thick-walled pipelines with carbon and low-alloy silicon-manganese steels with a temporary resistance of not less than 490 MPa, operating at a temperature up to 400 °C.
