Manufacture of superconducting radiofrequency (SRF) cavities for modern accelerators requires ultra-purity niobium. Joining components of such cavities is only possible with the use of electron-beam welding. Investigations on this topic ...
The results of metallographic studies of dissimilar materials welds joint’s structure are presented. Welds were obtained from steel (12Х21Н5Т in Russian) and bronze (БрХ-06 in Russian), using EBW with the oscillation of ...
Experimental results (four series of experiments) for EBW of two types of steel – high strength steel of 38Cr2Ni2Mo type and stainless steel are obtained and used for the estimation of models, describing the dependencies of the ...
Dissimilar welds are the integral part of design in chemical, nuclear and energy industries. One of the most common combinations is the joints between ferritic, austenitic and martensitic steels. These joints provide many advantages ...
The article is devoted to research of electron beam welding construction elements for International Thermonuclear Experimental Reactor in National Resesrch University “Mocow Power Engineering Institute”. It reviews design and technology ...
The mechanisms of the beginning of depth oscillations of the vapour-gas channel are examined in beam welding. It is assumed that the reasons of the root peaks are the evaporation and condensation of metal vapour in the channel. To test ...
The paper presents the approximate formulas for calculating the deflection angle and the misalignment of the electron beam from the optical axis of the electron gun caused by the action of magnetic fields during the electron beam welding. ...
We study methods of beam positioning at the joint during Electron Beam Welding in air. Traditional methods of automatic beam positioning at the joint are unacceptable during the Electron Beam Welding in air because of the significant ...
The characterization of the radial and the angular space distribution of particle trajectories (or respective current distributions) in powerful electron beams is an actual scientific and practical task, connected with the quality improvement ...
