Електроди зварювальні Моноліт ЦЛ-39

AWS A5.5: E8018-B2
EN ISO 3580-A- E CrMoV1 B 2 2
CONDITIONS OF USE
  • designed for welding in all spatial positions in a circumvertical way from top to bottom
SPECIAL PROPERTIES
  • provide high resistance of the weld metal to the formation of pores, lengthen the arc, allow welding with an inclined edge of the base metal of at least 15%
  • the welding seam is strong and resistant to scale formation
  • high heat resistance
  • ensures uniform strength welded joints of almost all grades of heat-resistant steels
  • the deposited metal is not prone to the formation of hot cracks
  • perform welding with a short arc, cleaning the edges before welding
  • surfacing coefficient: 0,13…0,15 g/A•min
  • consumption of electrodes per 1 kg of deposited metal: 1,4…1,6 kg
For manual arc welding on direct current reverse polarities of heating surfaces of boiler units, as well as root ones layers of seams, joints of thick-walled pipelines made of heat-resistant steels of the pearlitic class of grades 12Х1МФ and 15Х1М1Ф, operating under temperatures up to 585˚С.
