Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

Results of experimental studies of the connection between the processes proceeding in the electrode wire melting zone and electric parameters of the electroslag welding mode are described. The experimental procedure envisaged electroslag welding of specimens from 60 mm thick steel 09G2S the in modes identical to those, used earlier for photographing and filming the welding zone through an optically transparent medium. Hall sensor, ADC module E-140 and «Power Graph» software were applied for high-speed recording of electric parameters of mode (10 thou records per second). Measurements of slag pool temperature near the electrode wire melting zone were taken simultaneously. Analysis and comparison of visual observations of the welding zone through an optically transparent medium with the characteristics of electroslag welding mode (Uw, Iw, Vw.f) were performed, confirming the cyclic existence of some nucleus in the molten slag between the electrode wire and liquid metal, formed under the effect of electric potential between the base and electrode metal. 9 Ref., 4 Figures.
Keywords: electroslag welding, slag pool, interelectrode gap, high-speed recoding of electric parameters of mode, active zone, energetic nucleus, «discharge», melting and transfer of liquid metal, high-speed photographing and filming
