Abstract

U teorijskom dijelu rada obrađena je metoda konačnih elemenata koja se koristi kao ishodište aplikacija za simulaciju zavarivanja. Kratko su obrađene različite komercijalne aplikacije za simulaciju zavarivanja. Također, obrađuju se načini odabira dodatnog materijala i postupka zavarivanja. U zadnjem dijelu teoretskog dijela rada, obrađuju se deformacije, njihova podjela te načini sprečavanja njihovog nastanka. Eksperimentalni dio rada podijeljen je na dva dijela: realno i simulirano zavarivanje. Realni dio zavarivanja proveden je u Laboratoriju za zavarivanje na Fakultetu strojarstva i brodogradnje. Zavaren je sučeljeni spoj različitim dodatnim materijalima te je ispitan utjecaj dodatnog materijala na deformacije. Simulacija je provedena na osobnom računalu, u programskom paketu Visual-Environment-u te su dobiveni rezultati uspoređeni s realnim.

Abstract (english)

The theoretical part of the graduate thesis deals with the finite element method used as the starting point for the welding simulation application. Various commercial applications for welding simulations were processed. Also, the methods of selecting additional materials and welding procedures are being worked out. In the latter part of the theoretical part of the work, deformations, their division and ways of preventing their occurrence are treated. The experimental part of the work is divided into two parts: real and simulated welding. The real part of experimental work is carried out in the Laboratory of welding at Faculty of Mechanical Engineering and Naval Architecture. Butt welds were welded with variety of additional materials and it was examined the impact of additional material on deformation. Simulation was performed on a computer, in the Visual - Environment program package and results were compared to real.
