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.

Hybrid laser-microplasma welding is one of the modern innovative processes of welding sheet stainless steels, allowing minimization of residual deformations, producing high-quality and durable joints. In this study, basic techniques of hybrid laser-microplasma welding were optimized, mode parameters were précised, and mechanical properties and corrosion resistance of the produced joints of SUS 304 steel were assessed. The good prospects for application of laser-microplasma welding for joining thin stainless steels were confirmed experimentally. 6 Ref., 2 Tab., 10 Fig..
