Modelowanie łuku spawalniczego o zmiennej długości kolumny plazmowej

Abstract: Modelowanie łuku spawalniczego o zmiennej długości kolumny plazmowej Modeling of welding arc with variable plasma column length Dr hab. inż. Antoni Sawicki, prof. PCz-Polite-chnika Częstochowska. Streszczenie W artykule opisano modele Cassiego-Bergera i Kułakowa łuku elektrycznego o zaburzanej długości kolumny plazmowej. Przedstawiono nowy model hybrydowy łuku słuszny w zakresach słabych i silnych prądów, a także wyniki symulacji procesów w obwodzie z tym modelem, z wymuszeniem prądowym okresowym i z zaburzeni… Show more

“…The formation of near-electrode processes and borderline thermal layers on the scrap is greatly influenced by the vibrational processes which emerge from the interaction of acoustic energy with hard metal [3]. In such conditions, arc discharges cause mechanical destruction of metal, and arcs tend to cut and break the scrap rather than heat the metal [4][5][6][7][8][9][10][11][12][13].…”
