ABSTRACT / САЖЕТАК:
Ovaj rad ima za cilj da se uporede mehanička i strukturna svojstva sučeonih zavarenih svojstava različitih legure aluminijuma 2024-T351 i AA 6082-T6 dobijenih MIG i TIG postupkom zavarivanja. Legura AA 6082 T6 je dobro zavariva klasičnim fuzionim postupcima zavarivanja (MIG i TIG), dok je legura 2024-T351 gotovo nezavariva. Za zavarivanje ovih dveju različitih legura Al korišćeni su MIG i TIG postupak zavarivanja na limu debljine 8 mm koristeći dodatni materijal 4043A (AlSi5) i mešavinu argona i helijuma kao zaštitnog gasa za MIG postupak, odnosno čist argon za TIG postupak zavarivanja. U radu su uporedno data mehanička svojstva zavarenih spojeva dobijenih MIG i TIG postupkom zavarivanja. Uporedno je data mikrostrukturna evolucija zavarenog spoja različitih legure aluminijuma AA6082-T6 i AA2024-T351. Uporedno su data mehaničkih svojstava zavarenih spojeva različitih Al legure na osnovu rezultata ispitivanja tvrdoće prema Vikersu, ispitivanja na zatezanje i savijanja zavarenih uzoraka.
