The data transfer rate which in the near future will be provided by the 5G standard will allow to combine thousands of drones (unmanned aerial vehicles, UAV) in real time into a common network, capable of tracking any situation in the territory of a large metropolis (within the SmartCity project). The large number of UAVs which are in continuous operation in the airspace will lead to a situation where a variety of adverse climatic factors (high humidity, sudden gusts of wind, lightning minutes, electromagnetic fields, electron-ion irradiation, infrared heating, electrostatic discharge, corona discharge in the atmosphere, etc.) will influence on these UAVs. This can lead to systematic failure of this type of device which will lead to additional costs and deterioration of the quality of the system in general. Implementation in the drone-construction some systems similar to systems for protecting aircraft from lightning strikes (for example, the Faraday grille in the body) will lead to a significant increase in the costs of devices. Therefore, a develop proposals for measures to protect drones from such an impact, at the present stage of development, the diagnostic and prediction of the thermo-mechanical and strength characteristics of the component base of control systems of unmanned vehicles of a “smart city” using 5G technology when exposed to external electrical effects of considerable amplitude is of practical value.

This article provides information on the development of an adjustable spot welder implemented on the basis of the capacitor principle without a transformer. Also the scientific work considers the calculation of the energy of the capacitors for a spot welding apparatus using modern methods of numerical simulation and programming. The method of calculation is given, as well as a mathematical solution tool. The calculation results are compared with the experiment. Based on the data obtained, according to the results of calculations, work was carried out on a prototype, the result of which was an adjustable spot welder. It allows you to accurately and quickly weld nickel plates to lithium cells, creating full-fledged batteries from them, which are widely used in modern technology, including promising vehicles. The presence of sensors and a screen allows the operator to control the charging process and the direct operation of the unit, which simplifies the use of the device.
