APPLICATION OF PLASMA IN MECHANICAL ENGINEERING PROCESSES

U radu je predstavljena primjena plazme u strojarstvu. Općenito o plazmi, vrsti plazmenih plinova te kako uspostaviti električni luk. Govorimo o razlici između prenesenog i neprenesenog električnog luka te opisujemo postupke zavarivanja i rezanja plazmom. Navodimo vrste materijala koji se mogu obrađivati plazma postupkom te kako debljina i brzina rezanja utječe na kvalitetu zavarenih spojeva i reznih površina te na kraju navodimo primjer uspješne primjene plazme u izradi strojarskih proizvoda i konstrukcija.In this paper is introduced use of plasma in mechanical engineering. Generaly about plasma, different kinds of plasma gasses and how establish electrical arc. We are talking about difference between transformed and not transformed elektrical arc and discribing procedure of welding and plasma cutting. There is also a list with different kinds od materials which are used for plasma procedure and how thickness and speed affect quality of welded joints and cutting surface. On the end we list examples of successful use of plasma in mechanical engineering production and construction
