Abstract
The high-pressure heaters are the fundamentally necessary links of the second circuit of power units of nuclear power plants with light-water WWER-type reactors. They represent single-plane or two-plane pipe spirals of carbon steel. The paper presents the results of selection and mastering the mechanized welding technology for applying in the manufacture and restoration repair of high-pressure heaters. 20 Ref., 2 Figures.
Keywords: high-pressure heaters, spirals of high-pressure heaters, automatic welding, consumable electrode, electrode wire, mixture of shielding gases, technological equipment, rotary joints of pipelines, welding rotator
