Information × Registration Number 0205U004147, 0104U000600 , R & D reports Title The research of possibility to increase the cathodes life time in powerful electron welding guns by means of gas-dynamics processes control along the beam. popup.stage_title Head Nazarenko Oleg Kuzmich, Registration Date 02-03-2005 Organization E.O.Paton Electric Welding Institute of the National of Sciences of Ukraine popup.description2 Universal high voltage electron welding gun has been developed in which the throttle is installed under anode. The throttle has central norrle which is sloping towards the pump of differential pumping. The distance from anode to throttle is installed subject to pressure gradient near the gun axis and electric field sag into anode hole. As a result the Lab6-cathode life time is increased to 100 hours. Product Description popup.authors popup.nrat_date 2020-04-02 Close
