COATING TYPE — Basic
SPECIAL PROPERTIES
Excellent mechanical properties of deposited metal. Good welding-technological properties, easy slag crust removal and formation of a seam with smooth transition to the base metal.
APPLICATION CONDITIONS
Deposition rate factor: 11,0 g/A.hr. Electrode consumption per 1 kg of deposited metal is 1,6 kg. Applied for welding in all the spatial positions except vertical down, on reverse polarity DC. Welding should be done with a short arc, without lateral oscillations, clean the edges before welding.
REDRYING BEFORE WELDING
Redrying before welding: 200-250 °С for 2,0-2,5 hours.
