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.

Operation of underground lines has own peculiarities. The most critical element of track is the rails, in which joints are particularly stressed place. Decrease of number of bolted joints significantly reduces the probability of defect formation in the rails. Experience of the E.O. Paton Electric Welding Institute on application in Kyiv underground of a new method of rails joining, namely automatic consumable electrode electric arc bath welding, is presented. It provides high productivity of welding in comparison with alumothermal welding and required mechanical properties of the joints. Restoration of surface of the rails and parts of crossing pieces is recommend to be performed using semi-automatic arc surfacing with self-shielded flux-cored wire. 4 Ref., 1 Table, 3 Figures.
