ОБРАБОТКА МЕТАЛЛОВ Том 24 № 4 2022 48 ТЕХНОЛОГИЯ По результатам работы можно сделать вывод, что плазменная резка на токах обратной полярности является эффективной для резки проката больших толщин, однако методика требует дальнейшей отработки с целью повышения качества получаемого реза. В дальнейших работах планируется проведение сравнительных исследований в области плазменной резки листового проката больших толщин с использованием плазмотронов с прямой и обратной полярностью.
