Abstract
Ovim radom obrađen je konvencionalni MAG postupak zavarivanja kao i načini prijenosa metala koji se javljaju kod ovog postupka. Nadalje, nabrojani su i kratko opisani modificirani načini prijenosa metala koji se upotrebljavaju u industriji, a zasnivaju se na konvencionalnim načinima prijenosa. Detaljno je obrađen visokoučinski postupak MAG zavarivanja koji primjenjuje način prijenosa metala zakopanim lukom nazvan "D - Arc" kao i njegova primjena za zavarivanje debelostjenih konstrukcija od nelegiranih čelika. Eksperimentalni dio proveden je s ciljem usporedbe kvalitete zavara dobivenih visokoučinskim D - arc postupkom zavarivanja u odnosu na konvencionalni štrcajući luk te optimizacije parametara zavarivanja za D - arc sustav. Ispitivanja su se sastojala od vizualne analize makroizbruska, mjerenja tvrdoće te radiografskog snimanja zavara.
Abstract (english)
This thesis deals with the conventional MAG welding process as well as the methods of metal transfer that occur in this process. In addition, the modified metal transfer modes which are used in industry, based on conventional metal transfer modes are listed and shortly described. High-efficiency MAG welding process which applies "buried arc" metal transfer mode also called "D-Arc" has been elaborated in detail as well as its application for welding thick steel structures of non-alloy steel. The experimental part of the thesis was performed with the aim of comparing the quality of weld obtained by high-efficency D - arc welding process in relation to the conventional spray arc and optimizing the welding parameters for the D - arc system. The tests consisted of visual macroscopic analysis, hardness measurements and radiographic imaging. After the tests were carried out the obtained results were compared with the conventional spray transfer.
