Електроди зварювальні МР-3

AWS А5.1: Е6013
EN ISO 2560-A-E 38 0 R 1 2
CONDITIONS OF USE
  • intended for welding corner, butt and filler metal seams up to 20 mm thick
  • diameters from 2.5 to 4 mm are suitable for welding in all spatial positions, except vertical from top to bottom
  • electrodes with a diameter of 5 mm - for the lower position, horizontal on the vertical plane and vertical from the bottom up
  • welding must be carried out with a direct current of reverse polarity or alternating current from a transformer with a voltage of 70±10 V idle
SPECIAL PROPERTIES
  • ensure high-quality formation of the weld metal, resistance of the deposited metal to the formation of pores and hot cracks, as well as easy overlapping of gaps
  • excellent welding and technological properties ensure easy initial and re-ignition of the arc when applying tacks, as well as good and stable burning of the arc, small losses of metal from splashing, uniform melting of the coating, easy separation of the slag crust
  • welding with an elongated arc on an oxidized surface is allowed
  • highly appreciated by welders both in industry and in for domestic use
  • surfacing coefficient: 0.14...0.16 g/A•min
  • consumption of electrodes per 1 kg of deposited metal: 1.5...1.6 kg
MP-3 electrodes are designed for manual arc welding of chain structures made of low-carbon grades of steel, which are set according to DSTU 2651/GOST 380 (Article 0, Article 1, Article 2, Article 3 of all groups A, B, B and all degrees of deoxidation - "KP", "PS", "SP") and according to DSTU 7809 (05kp, 08kp, 08ps, 08, 10kp, 10ps, 10, 15kp, 15ps, 15, 20kp, 20ps, 20).
