ABSTRACT:
The welding electrode rotates at variable speed about the axis of the cylindrical part so as to lay down successive superposed layers, each covering the entire width of the bevel. The electrode is moved translationally in the direction of the axis of the cylindrical part. The device includes arrangements for adjusting the speed of rotation of the electrode and for moving it in the direction of the axis. The method may be used for welding a replacement adaptor onto the vessel head of a nuclear reactor.
