Abstract

U ovom diplomskom radu provedena je komparativna analiza zavarenih spojeva bakra Cu-ETP i aluminijske legure serije 1050 izvedenih na disk laseru i fiber laseru.
U teorijskom dijelu rada opisan je baterijski sustav električnih vozila te primjena raznorodnih materijala u navedenom području. Detaljno je opisano lasersko zavarivanje s naglaskom na fiber i disk laser te mikrostrukturne promjene koje nastaju pri zavarivanja aluminija i bakra.
U eksperimentalnom dijelu rada provedena je analiza makrostrukture, mikrostrukture te mjerenje mikrotvrdoće HV0,01 na zavarenim spojevima bakra i aluminijske legure.
Navedenim postupcima, osobito mjerenjem mikrotvrdoće HV0,01, moguće je provesti kvalitetnu karakterizaciju zavarenih spojeva izvedenih na disk i fiber laseru te utvrditi sličnosti i razlike među njima.

Abstract (english)

In this thesis, a comparative analysis of welded joints of Cu-ETP copper and aluminum alloy series 1050 performed using disk and fiber lasers, was carried out.
The theoretical part of the thesis describes the battery system of electric vehicles and the application of dissimilar materials in this field. Laser welding is explained in detail, with an emphasis on fiber and disk lasers, as well as the microstructural changes that occur during the welding of aluminum and copper.
In the experimental part, an analysis of macrostructure, microstructure, and HV0.01 microhardness measurements on welded joints of copper and aluminum alloy, were carried out.
With these methods, especially by measuring the microhardness HV0.01, it is possible to carry out characterization of welded joints performed on disc and fiber laser, and to determine similarities and differences between them.
