Abstract

U teorijskom dijelu rada opisana je podjela aluminijskih legura, njihove karakteristike i
problematika zavarljivosti aluminijskih legura s posebnim osvrtom na primjenu aluminijskih
legura u brodogradnji. Detaljno je opisan TIG postupak zavarivanja te je objašnjena
klasifikacija osnovnih vrsta spojeva koji se primjenjuju pri izradi brodskih konstrukcija. U
posljednjem dijelu teorijskog rada dan je pregled pripreme spojeva za zavarivanje
aluminijskih legura prema normi HRN EN ISO 9692-3.
U eksperimentalnom dijelu rada odabrana je tehnologija zavarivanja aluminijske legure
6082 T6. Strojnom obradom sukladno normi HRN EN ISO 9692-3 pripremljene su dvije
cijevi. Provedeno je zavarivanje radnih komanda AC TIG postupkom. Naposljetku su
provedena ispitivanja radiografskom metodom, statično-vlačni pokus i ispitivanje savijanjem
te je izvršena makroskopska analiza. Na temelju dobivenih rezultata eksperimentalnog rada
donesen je zaključak.

Abstract (english)

The theoretical part of this thesis deals with the division of the aluminum alloys, their
characteristics and weldability problems, with special reference to the application of
aluminum alloys in shipbuilding. The TIG welding process is described in detail. Moreover,
the classification of the basic types of joints used in the construction of the ship structures is
explained. An overview of the preparation of joints for welding aluminum alloys according to
the HRN ISO 9692-3 standard is given in the last part of the theoretical work.
In the experimental part the suitable welding technology has been chosen for welding
aluminum alloy 6082 T6. Two pipes were prepared by machining accordingly to the
HRN ISO 9692-3. Butt welding of pipe was done using the AC TIG technology. Ultimately,
tests were carried out using the radiographic method, static tensile test and bending test, along
with performing macroscopic analysis. Based on the obtained results of the experimental
work, a conclusion was made.
