Abstract

U završnom radu opisan je je MAG postupak zavarivanja te je navedena i objašnjena oprema koja se koristi u postupku, parametri zavarivanja i najčešće greške. Uz to, dan je pregled i opis načina prijenosa metala i modificiranih postupaka zavarivanja. Također su iznesene teorijske osnove dinamičke karakteristike i načina izračuna unesene topline.

U radu su prezentirani rezultati eksperimentalnog dijela u kojem je provedeno mjerenje dinamičkih karakteristika za metode prijenosa metala kratkim spojevima, impulsnim lukom i ColdArc postupkom. Dobiveni podaci su potom analitički obrađeni te je izračunat unos topline koji je uspoređen s unesenom toplinom izračunatom uobičajenim načinom u skladu s normom HRN EN 1011-1.2009. Dobiveni rezultati i odstupanja su grafički prikazani i analizirani na temelju prethodno stečenih znanja.

Abstract (english)

In this thesis MAG welding procedure is described as well as related equipment, welding parameters, welding defects and metal transfer modes including few most common modified procedures. Also theoretical basics of dynamical characteristics and input energy calculation are included.

Thesis presents results obtained in the experimental part of the work while measuring dynamic characteristic for Short Arc, Pulsed Arc and ColdArc procedure. The data is analytically processed, and heat input is calculated accordingly. Also the heat input calculated from dynamic characteristic is compared with heat input calculated following norm HRN EN 1011-1.2009. Results are graphically presented and analysed according to the previously acquired knowledge.
