Abstract
U okviru ovog diplomskog rada prikazane su osnovne karakteristike i primjena aluminijskih legura s naglaskom na legure serije 5XXX i 6XXX. Prikazane su osnovne značajke zavarljivosti aluminijskih legura kao i pogreške koje mogu nastati prilikom njihova zavarivanja. Također u sklopu teoretskog dijela rada prikazane su osnovne značajke MIG postupka s naglaskom na načine prijenosa metala prilikom zavarivanja aluminijskih legura. Dodatno je opisana primjena konvencionalnih pulsnih struja i prijenosa metala duplim pulsom, kao i dinamičke karakteristike tih dvaju metoda. U eksperimentalnom dijelu rada određena je dinamička karakteristika izvora struje pri zavarivanju aluminijske legure 5083 korištenjem pulsnog prijenosa i prijenosa duplim pulsom. Uz to izvedeni su kutni zavari aluminijskih ploča legure 5086 primjenom dvaju spomenutih načina prijenosa metala, nakon čega su provedena ispitivanja propisana normom HRN EN ISO 15614-2. Na temelju dobivenih rezultata provedena je komparativna analiza konvencionalnog pulsnog postupka i postupka duplim pulsom.
Abstract (english)
Within this thesis, aluminium alloys’ basic characteristics and application emphasising alloys of series 5XXX and 6XXX are presented. The essential weldability characteristics of aluminium alloys and the errors that can occur during their welding are shown. Also, as part of the theoretical part of the paper, the basic features of the MIG process are presented, with an emphasis on the methods of metal transfer during welding of aluminium alloys. The application of conventional pulse currents and double-pulse metal transfer is additionally described with the dynamic characteristics of these two methods. In the experimental part of the paper, the current source’s dynamic characteristic during welding of aluminium alloy 5083 was determined using pulse transmission and double pulse transmission. Besides, angular welds of aluminium plates of alloy 5086 were performed using the two mentioned metal transfer methods after which the tests prescribed by the standard HRN EN ISO 15614-2 were performed. A comparative analysis of the conventional pulse procedure and the double pulse procedure was performed based on the obtained results.
