dc.description.abstract | Smanjenje otvora žljeba može značajno doprineti efikasnosti zavarivanja i produktivnosti teških metalnih konstrukcija Uobičajena je upotreba uglova žljeba od 45° i 60°. Smanjenje ugla otvora žljeba smanjuje potreban broj zavara, čime se smanjuje trajanje zavarivanja, potrošnja materijala za ispunu i zaostali naponi i deformacije. Međutim, smanjivanje ugla žljeba dovodi do određenih poteškoća. Teško je kontrolisati luk u uskom žljebu, što može dovesti do problema sa kvalitetom spoja. U ovom radu je prikazano zavarivanje sučeonih spojeva od čelika debljine 22 mm sa uglom žljeba od 20°. Zavarivanje je izvršeno korišćenjem MAG postupkom zavarivanja, uz softversku kontrolu luka. | sr |
dc.description.abstract | Reduction in groove opening can significantly contribute to welding efficiency and productivity of heavy metal structures. It is common practice to use welded joint groove angles of 45° and 60°. Reduction of the groove opening angle decreases the necessary number of welding passes, thus decreasing the welding duration, filler material consumption and residual stresses and strain. However, groove angle reduction leads to certain difficulties. It is hard to control the arc in a narrow groove, which could lead to welded joint quality issues. In this paper, welding of butt joints made of 22 mm thick steel with the groove angle of 20° is shown. Welding was performed using the MAG procedure, with software controlled ar. | en |
