Welding electrodes RS-39

designed for welding in all spatial positions in a circumvertical way from top to bottom

Special properties

provide high resistance of the weld metal to the formation of pores, lengthen the arc, allow welding with an inclined edge of the base metal of at least 15%
the welding seam is strong and resistant to scale formation
high heat resistance
ensures uniform strength welded joints of almost all grades of heat-resistant steels
the deposited metal is not prone to the formation of hot cracks
perform welding with a short arc, cleaning the edges before welding
surfacing coefficient: 0,13…0,15 g/A•min
consumption of electrodes per 1 kg of deposited metal: 1,4…1,6 kg

For manual arc welding on direct current reverse polarities of heating surfaces of boiler units, as well as root ones layers of seams, joints of thick-walled pipelines made of heat-resistant steels of the pearlitic class of grades 12Х1МФ and 15Х1М1Ф, operating under temperatures up to 585˚С.
