Abstract
Ovaj rad se bavi usporedbom zavarenih spojeva dobivenih s dva različita postupka MIG zavarivanja na kutnom spoju od aluminijske legure. Postupci zavarivanja koji će se uspoređivati su konvencionalno impulsno MIG zavarivanje s istosmjernom strujom i AC MIG zavarivanje, oba postupka koriste čisti argon kao zaštitni plin. Za korištene postupke zavarivanja opisan je princip rada i navedene su prednosti koje isti imaju. Za korištenu aluminijsku leguru opisane su greške koje se mogu pojaviti prilikom zavarivanja, analizirana je problematika smanjenja čvrstoće u području zavarenog spoja te faktori koji mogu utjecati na kritično područje. U eksperimentalnom dijelu rada korišteni su limovi aluminijske legure EN AW 6082-T6 duljine 250 mm i debljina od 6 i 10 mm. Ovisno o debljini osnovnog materijala napravljeni su zavari, u jednom prolazu, s određenim vrijednostima nominalnog nadvišenja. Za svaki postupak zavarivanja napravljena su dva kutna zavarena spoja na kojima su provedena ispitivanja makrostrukture i analiziran je utjecaj postupka na širinu zone utjecaja topline na temelju profila tvrdoće. U komparativnoj analizi uspoređene su prednosti AC MIG i MIG-P postupka zavarivanja, određeni su parametri zavarivanja kako bi se dobila odgovarajuća konfiguracija i dimenzija kutnog spoja. Zaključno se donosi preporuka za primjenu postupka kod zavarivanja konstrukcija od zadane aluminijske legure.
Abstract (english)
The topic of this master thesis is the comparison of the welded joints produced with two different MIG welding processes on a T-joint from aluminium alloys. The welding processes being compared are conventional pulsed MIG with direct current and AC MIG welding. Both processes use pure argon as a shielding gas. For the welding processes used, the working principle is described and their advantages are listed. Possible welding defects for the used aluminium alloy were explained. The problem of strength reduction around the welding joint and the factors that affect the intensity and width of the critical area were analysed. In the experimental part of the work, plates of aluminium alloy EN AW 6082-T6 were used in the length of 250 mm and in 6 mm and 10 mm of thickness. Depending on the plate thickness, welds were made in one pass with certain values of the nominal weld height. For each welding procedure two T-joint welds were made on which macrostructure tests were carried out, and the influence of the procedure to the width of the heat-affected zone was analysed based on a hardness profile. In the comparison analysis, advantages of AC MIG and MIG-P welding process were compared. Welding parameters were proposed based on achieving targeted weld configuration and dimensions of the weld joint. In conclusion, a recommendation was given for the application of the process when welding structures made of the given aluminium alloy.
