Abstract

U ovom diplomskom radu provedena je detaljna usporedba zavarenih spojeva između niskougljičnog čelika prevučenog niklom (Hilumin) i aluminijske legure serije 1050, izvedenih na disk i fiber laseru.
Teorijski dio rada obuhvaća opis principa rada lasera, klasifikaciju i karakteristike različitih tipova lasera, metode ispitivanja laserski zavarenih spojeva te specifičnosti zavarivanja raznorodnih materijala.
U eksperimentalnom dijelu rada provedena je analiza makrostrukture i mikrostrukture te mjerenje mikrotvrdoće HV0,01 u osnovnim materijalima, zoni utjecaja topline i metalu zavara, na zavarenim spojevima s oba tipa lasera. Nakon analize i usporedbe dobivenih rezultata doneseni su zaključci o prednostima i nedostatcima zavarivanja na disk i fiber laseru.

Abstract (english)

In this thesis, a detailed comparison was conducted of welded joints between nickel-coated lowcarbon steel (Hilumin) and aluminum alloy series 1050, performed using disk and fiber lasers, was conducted.
The theoretical part of the thesis includes a description of the principles of laser operation, the classification and characteristics of different laser types, methods for testing laser-welded joints and the specific challenges of welding dissimilar materials.
In the experimental part, an analysis of macrostructure and microstructure was conducted, along with HV0.01 microhardness measurements in the base materials, heat-affected zone and weld metal of the welded joints with both types of lasers. Following the analysis and comparison of the obtained results conclusions were drawn about the advantages and disadvantages of welding with disk and fiber lasers.
