Electron guns for processing applications typically use a thermionic cathode as the source of electrons, where the cathode is a resistively heated refractory metal ribbon. In order to keep the heat input to the gun reasonably ...
High power electron beam welding can be applied to structures such as pressure vessels with wall thicknesses of up to 200 mm. Such applications often make use of steels that exhibit ferromagnetic properties. If the work pieces ...
In this paper the electron beam welding of Ti–6Al–4V thin plates is simulated by implementation of a moving linear heat source model. The simulation results are used for estimation of regression models for the dependencies ...
In this paper the simulation of electron beam welding of Inconel 718 thin plates by a moving linear heat source is considered. Regression models for the molten pool geometry characteristics, depending on the electron beam ...
In this paper an experimental study of the geometrical characteristics of the cross-sections of the thermally affected areas obtained by electron beam welding joints of carbon steel grade 45 is made. The thermally affected ...

In this paper, analytical formulas for the computation of the field apparent resistivity of the soil for driven-rod electrodes are presented. General four driven-rod electrode array configuration and its special cases: general ...
In this paper we proposed a system for AC current monitoring in home appliances, up to 20A. System also measures voltage, line frequency, power factor, active power, and total imported active energy. The accuracy of the realized ...
In this paper, the analysis of magnetic field distribution of shielded copper conductor with the current of 100 A RMS is presented. The impact of various shielding materials (copper, aluminium and zinc-coated iron tin) and ...
