Electron beam welding (EBW) presents significant advantages in terms of welding performance when compared to other welding processes due to its small spot size, low divergence, high power density and low heat input. It is ...
The quality of electron beam welds depends upon a number of parameters like accelerating voltage, beam current, focus settings, vacuum level, working distance and welding speed. Even if these parameters are tightly controlled, ...
Measurements of electron beam profiles always had an academic touch in the past. New standards and faster image processing make the beam characterization more and more a quality tool in production and allow transfer of beam ...
In this work the automatic control of the vacuum and cooling systems, together with electron beam initiation, of the located in the IE-BAS equipment for electron beam welding, evaporation and surface modification by SIMATIC ...
The Thailand Center of Excellence in Physics is an organization under the Ministry of Education aiming at promoting physics research in local Thai universities. Particle beam and plasma physics is one of the emphatic fields ...
The electron gun plays an important role in atomic, molecular, plasma, thin film, lithography and surface physics. Different types of electron gun have been designed for producing different electron beam energies. Cylindrical ...
BINP (Budker Institute of Nuclear Physics, Novosibirsk, Russia) have successfully used the electron beam welding for manufacturing of vacuum chambers for a long time. The EBW facility provides the maximum seam length of 2 ...
This paper presents a new design of new EBW machine. Newly developed EBW machine is intended primarily for welding of massive components large power units as well as series of smaller weldments. The volume of the welding chamber ...
The paper presents an automated wide-aperture (750×150 mm) plasma cathode electron source based on a low-pressure arc with grid stabilization of the plasma emission boundary and beam extraction into the atmosphere or high-pressure ...
