Електроди зварювальні АНО-21

AWS А5.1: Е6013
EN ISO 2560-A-E 38 0 R 1 1
CONDITIONS OF USE
  • intended for welding corner and butt joints with a metal thickness of up to 20 mm in all spatial positions, including vertical seams from top to bottom, except for electrodes with a diameter of 5.0 mm (for the lower position, horizontal on the vertical plane and vertical from below upward)
  • welding of vertical seams by the top-down method is carried out with a short arc or abutment, the electrode must be located in the plane that divides the angle of the welding parts and the angle of elevation of the electrode to the vertical must be 40...70°
  • when welding in the lower position, it is recommended to tilt the electrode in the direction of welding by 20...40° from the vertical, so that the arc is directed into the bath, to prevent slag from flowing into the bath
SPECIAL PROPERTIES
  • are distinguished by easy initial and re-ignition, as well as soft and stable arc burning, ensure low metal loss from spattering, uniform coating melting, excellent weld metal formation, easy separation of the slag crust
  • welded the metal is characterized by high resistance to external influences even at low temperatures
  • can be used for welding water pipes and low-pressure gas pipelines
  • provide fine flaking and a smooth transition from the base metal to the weld metal
  • surfacing coefficient: 0.13...0.15 g/A•min
  • consumption of electrodes per 1 kg of deposited metal: 1.4...1.5 kg
АНО-21 electrodes are designed for manual arc welding structures made of carbon grades of steel supplied according to DSTU 2651/GOST 380 (Art 0, Art 1, Art 2, Art 3 of all groups A, B, B and all degrees of acidification - "KP", "PS", "SP") and according to DSTU 7809 (05kp, 08kp, 08ps, 08, 10kp, 10ps, 10, 15kp, 15ps, 15, 20kp, 20ps, 20).
