Abstract
U ovom radu obrađen je postupak AC MIG i njegove prednosti u odnosu na konvencionalni MIG. Detaljno je objašnjena problematika izmjenične struje, njene prednosti i upotreba u MIG/MAG zavarivanju. Prikazan je i utjecaj polariteta struje na MIG postupak. Objašnjen je utjecaj balansa i frekvencije izmjenične struje na geometriju zavara. Također su objašnjeni problemi kod zavarivanja aluminija te koje je sve probleme moguće riješiti postupkom AC MIG u zavarivanju aluminija tanjih debljina. U eksperimentalnom dijelu rada provedeno je automatizirano AC i DC impulsno MIG navarivanje 6 uzoraka aluminijske legure 5083. Nakon navarivanja provedena je analiza deformacija u ovisnosti o vrsti struje i značajkama izmjenične struje tj. frekvencije i balansa polariteta. Izrađeni su makroizbrusci na kojima je ispitivana ovisnost geometrije zavara o značajkama izmjenične struje. Na temelju rezultata provedena je analiza te je pokazana ovisnost geometrije i deformacija zavara o značajkama izmjenične struje, te je uspoređen AC i DC MIG postupak te je pokazano da AC daje bolje rezultate, bolju kontrolu procesa i manje deformacije kod zavarivanja aluminija.
Abstract (english)
The subject of this paper is the AC MIG process and its advantages over conventional MIG. The problem of alternating current, its advantages and use in MIG/MAG welding are explained in detail. The influence of current polarity on the MIG procedure is also presented. It also explains the influence of balance and frequency of alternating current on weld geometry. Problems in aluminium welding are also described and what problems can AC MIG solve in welding thinner aluminium. In the experimental part of the work, automated AC and DC pulse MIG welding of 6 samples of aluminum alloy 5083 was performed. After welding, deformation analysis was carried out to determine the dependence of deformations on current type and characteristics of alternating current, EN ratio and frequency. Macrographs were made to determine the dependence of the weld geometry on the characteristics of alternating current. Based on the results, the analysis was performed and the dependence of the geometry and deformation of welds on the characteristics of alternating current was shown, and the AC and DC MIG procedure were compared and it was shown that AC gives better results, better process control and less deformation in aluminium welding.
