Abstract
The paper analyses the experience of development and application of highly efficient equipment for sealing fuel elements in WWER type reactors, using resistance welding. A two-position unit, that simultaneously processes two fuel elements in the automatic mode, has been developed on the basis of ASSK automatic welding machines and is being used successfully. The operation of the unit is provided by control system, pneumatic system, system of pumping down and filling the fuel elements with helium, as well as welding power source that are common for both the welding heads. These units were the basis to develop highly efficient automated lines for welding and sealing the fuel elements
Keywords: resistance welding, fuel element, sealing, automatic machine, unit
