AB  - Analiziran je uticaj zaštitnog gasa, na žilavost metala šava aluminijumske legure AlMg4.5Mn dobijenog MIG/MAG postupkom zavarivanja. Za merenje žilavosti je korišćeno instrumentirano Šarpijevo klatno sa mogućnošću razdvajanja energije nastanka i energije rasta prsline. Za MIG/MAG zavarivanje korišćene su četiri različite zaštitne atmosfere: čist Ar, kao i mešavine gasova Ar + 0,0307 % O2, Ar + 30 % He + 0,0317 % O2 i Ar + 48 % He + 0,0290 % O2. Metalografska ispitivanja su urađena da bi se ispitala pojava grešaka i poroznosti metala šava, a žilavost metala šava je ispitana na različitim temperaturama (20, - 90, - 196 °C). Na ovaj način je dobijen sveobuhvatan uvid u uticaj zaštitnog gasa na žilavost metala šava kao najkritičnije oblasti zavarenog spoja legure AlMg4.5Mn.
AB  - The effect of MIG/MAG shielding gas on the toughness of aluminium alloy AlMg4.5Mn weld metal has been analyzed using the instrumented Charpy pendulum for standard toughness testing. The MIG/MAG welding was performed in the shielded atmosphere of Ar, as well as the mixtures of gases Ar + 0.0307 % O2, Ar + 30 % He + 0.0317 %O2 and Ar + 48 % He + 0.0290 % O2. Metallographic tests have been performed in order to check the appearance and porosity of the weld metal, as well as its toughness testing at different temperatures (20, - 90, - 196 °C), using the instrumental Charpy pendulum, in order to separate the crack initiation and crack growth energy. In this way, a comprehensive insight of the effect of shielding gas on the weld metal toughness has been obtained.

AB  - The experiment have been performed using samples of welded joints of the three components aluminium alloy AlMg4,5Mn. The welding was performed with GTAW in the shielded atmosphere of Ar+0,015N2, mixture of the inert gases Ar+50%He+0,015N2 and Ar+70%He+0,015N2. After welding has been completed, the metallographic tests, the tensile test and the tests of the hardness were performed. Also, the weld metal toughness was estimated, using the instrumental Charpy impact testing system, followed by estimating the crack initiation energy, crack growth energy and the fracture mechanics parameters. The goal was to establish the effects of shielding atmosphere composition on the mechanical properties and fracture mechanics parameters of weld metal.

AB  - Poroznost predstavlja ozbiljan problem zavarenih spojeva legura Al, jer se zbog toga značajno smanjuje mogućnost primene Al legura za izradu lakih konstrukcija. Da bi se poroznost smanjila ispitani su zavareni spojevi legure AlMg4,5Mn i analizom mikrostrukture je utvrđen uticaj sastava zaštitnog gasa primenjenog TIG postupka na poroznost metala šava. Na osnovu te analize je ocenjen kvalitet izvedenog zavarenog spoja. Kao zaštitni gasovi su korišćeni Ar, He i N2, samostalno ili u vidu mešavina. Najveća poroznost se dobija pri upotrebi čistog argona, a najbolji rezultat je dobijen mešavinom Ar + 50%He + 0,015%N2. .
AB  - Porosity represents a serious problem of welded joints of Al alloys, since it significantly reduces their applicability for producing light structures. In order to reduce porosity, welded joints of AlMg4.5Mn alloy have been tested and how the weld metal porosity is influenced by the shielding gas composition in the applied TIG process is also determined by microstructural analysis. Based on this analysis, the performed welded joint is quality assessed. Shielding gases Ar, He and N2 were used, individually, or in mixtures. Highest porosity is achieved with pure argon, and the best results with a mixture Ar + 50%He + 0.015%N2. .
