Recent work completed for ESA and Ariane Group performed a comprehensive comparative assessment of laser and electron beam processes, targeting stainless steel flow control valve materials and typical penetrations to determine ...
This article discusses a modeling approach for the obtained by electron beam welding molten pool shapes, which is based on experimental data, type mathematical function and regression analysis. The process of electron beam ...
We report in this paper a systematic study for partial penetration of the electron beam welding and its correlation with the beam power as a combination of beam voltage and current, welding speed and working distance. The ...
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 ...
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 ...
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 ...
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 ...
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 ...
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. ...
