Abstract

Aluminij je metal koji je nakon kisika i silicija najrasprostranjeniji element u Zemljinoj kori s udjelom od 8%. Na izložbi u Parizu 1855. godine prvi put je predstavljen u elementarnom stanju. Aluminij je srebrno-bijeli metal koji pripada skupini lakih metala i jedan je od najprimjenjivijih materijala. U Zemljinoj kori ne postoji u elementarnom stanju, nego se dobiva elektrolizom iz aluminijevog oksida (glinice) Al2O3. Karakteriziraju ga mala gustoća, nisko talište i jako dobra provodljivost električne i toplinske energije. [10]
Budući da je aluminij izuzetno mekan i krhak, u industriji se uglavnom koriste njegove legure. Najčešći legirni elementi aluminija su magnezij, mangan, silicij, bakar i cink. U nastavku će kroz poglavlja biti detaljnije objašnjena svojstva i primjena Al i Al legura, naročito Al legure EN AW 5083 H111. Detaljno će se razraditi svi postupci elektrolučnog zavarivanja koji su primjenjivi za zavarivanje Al i Al legura te način pripreme spoja i moguće pogreške.
U eksperimentalnom dijelu rada prikazani su i analizirani rezultati ispitivanja mehaničkih svojstava sučeonog spoja limova aluminijeve legure EN AW 5083 H111 prema zahtjevima norme HRN EN ISO 15614-2:2007.

Abstract (english)

Aluminum is a metal that, after oxygen and silicon, is the most abundant element in the Earth's crust with an 8% share. At the exhibition in Paris in 1855 it was presented for the first time in elementary shape. Aluminum is a silver-white metal that belongs to a group of light metals and is one of the most applicable materials.Aluminum does not exist in elementary shape in Earth's crust so it is obtained by electrolysis of aluminum oxide (alumina) Al2O3. It is characterized by low density, low melting point and a very good conductivity of electricity and heat. [10]
Since aluminum is exceptionally soft and fragile its alloys are mainly used in the industry. The most common alloying elements of aluminum are magnesium, manganese, silicon, copper and zinc. The properties and application of aluminum and aluminum alloys will be explained indetail especially aluminum alloy EN AW 5083 H111. All welding procedures of aluminum and aluminum alloys will be considered in detail.
According to the requirements of HRN EN ISO 15614-2:2007, in the experimental part will be presented and analyzed the results of testing mechanical properties of aluminum alloy EN AW 5083 H111.
