Welding electrodes RS-5 Plasma

AWS A5.1: E7016-1 H8

EN ISO 2560-A-E 42 5 B 2 2 H10

welding should be carried out with a direct current of reverse polarity, (+) on the electrode, without preheating and subsequent heat treatment only on a short length of the arc along the cleaned edges

Special properties

provide high resistance of the weld metal to the formation of pores during arc extension, allow welding of the root seam of thick-walled pipes with a large gap
perform welding with a short arc, cleaning the edges before welding
surfacing coefficient: 0,13…0,16 g/A•min
consumption of electrodes per 1 kg of deposited metal: 1,4…1,5 кг

For welding elements of heating surfaces of boiler units, a also root layers of seams, joints of thick-walled pipelines with carbon and low-alloy silicon-manganese steels with a temporary resistance of not less than 490 MPa, operating at a temperature up to 400 °C.
