Welding electrodes Monolith 8018-B2

AWS A5.5: E8018-B2
CSA W48:E5518-B2
EN ISO 3580-A- E CrMoV1 B 2 2
Terms of use
  • designed for welding in all spatial positions except vertical down one.
Special properties
  • provide high resistance of the weld metal to pores formation during arc extension, allow welding with base metal edges inclination of at least 15%;
  • the welding seam is strong and resistant to scale formation;
  • high heat resistance;
  • provides uniform joints of almost all grades of heat-resistant steels;
  • deposited metal is not subject to the formation of hot cracks;
  • perform short-arc welding with prior cleaning of edges.
For manual DC arc welding of reverse polarity of boiler heating surfaces, as well as root welding, joint welding of heavy wall pipelines made of heat-re- sistant pearlitic steels operating at temperatures of up to 585˚С (1085˚F).
