Abstract

Tema ovog završnog rada je „ Značajke modernih izvora struje za MAG zavarivanje“ i sastoji se od teorijskog i eksperimentalnog dijela.

U teorijskom dijelu rada opisani su izvori struje za MAG zavarivanje sa naglaskom na statičku i dinamičku karakteristiku. Posebno je analiziran način određivanja parametara uz pomoć sinergijskih karakteristika. Opisane su specifične funkcije koje kompenziraju pad jakosti struje ovisno o slobodnom kraju žice te mogućnosti koje stabiliziraju i unaprjeđuju proces zavarivanja.

U eksperimentalnom dijelu na izvoru struje Fronius TPS 320i provela su se ispitivanja utjecaja kvalitete sinergijske karakteristike i funkcija za kompenziranje pada struje ovisno o slobodnom kraju žice. Analizirana je funkcija Korekcija visine luka (eng. Arc length correction), te se provelo ispitivanje navedene funkcije za različite slučajeve slobodnog kraja žice.

Abstract (english)

Topic of this thesis is „Characteristics of modern MAG welding power sources“. It consist of two parts, theoretical and experimental.

In the theoretical part MAG welding power sources and their statical and dinamical characteristics is decribed. Determination of welding parameters by synergic characteristics is described too. Specifical functions that compensates deviations of electrical current depended of wire height and possibilities to stabilisation and development of welding process.

In experimental part of work, tests on power source Fronius TPS 320i has been made. Test was about quality and influence of synergic characteristics and compensations of deviations for electrical current dependet of wire height. Arc length correction function is analyzed too and it was been tested for various amount of wire height.
