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.

In automation of consumable electrode arc welding it is necessary to have a clear knowledge about the structure of system for a self-regulation of the electrode melting rate. In the given work a general structure of this system is constructed on the basis of analytical description of dynamic processes, proceeding in the welding circuit. A simple structure analysis allows easy obtaining the necessary characteristics of the self-regulation system, including accuracy in a steady mode and time of optimizing the effect of disturbances. Criteria are suggested, that allow selecting those parameters of welding processes from the admissible values, which provide the desirable quick-response of the self-regulation system. Results of comparison of quick-response estimates, obtained by using these criteria, with results of computer modeling, are given. 21 Ref., 5 Figures.
Keywords: robotic arc welding, consumable electrode, structure of self-regulation system, evaluation of accuracy and quick-response of system
