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.

The problem of the general evaluation of a technical condition of main longitudinal beams of the E.О. Paton bridge was considered based on the results of selective non-destructive testing of truss elements. It is shown that the main cause of damage to the elements of the main beams is the corrosion of the nodal welded joints in the places of debris accumulation. High quality welded butt joints made by automatic and semi-automatic submerged arc welding was noted. 10 Ref., 18 Fig.
