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 ...
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 ...
Diabeam – potential for online quality control in electron beam welding
Currently, several hundred machines for electron beam welding are applied in Europe, especially in the fields of research and development, aircraft ...
In this paper the method of experimental estimation of the temperature in a keyhole in electron beam welding is described on the basis of chemical elements concentration in the vapors above welding zone. The temperature of ...
The conventional systems for control of throughout welds used beam current, that is passing through the crater in the liquid metal to the space on the back side of sample. In this paper a collector, situated not opposite the ...
Measurements of fluctuations of the ion current, collected by the plasma, generated during electron beam welding and treatment of the acquired data with modern digital methods are executed. Through the application of Coherent ...
It is described a model of plasma formation in the crater in liquid metal as well as above electron beam welding zone. Model is based on solution of two equations for density of electrons and mean electron energy. The mass ...
At present the area of industrial application of electron beam technology is constantly expanding. Today, there are new materials, technologies and standards, and thus approaches to the design of electron beam systems must ...
The distribution of thermal fields is simulated with the thermal action of the electron beam on stainless steel. To obtain data on the temperature distribution in the material, thermal loads are modeled. Two heating options ...
