Abstract
U teorijskom dijelu rada opisani su postupci zavarivanja svornjaka s detaljnim uvidom u postupak elektrolučnog zavarivanja svornjaka s odmakom luka uz primjenu keramičkog prstena ili zaštitnog plina (postupak 783). Također, detaljno su opisane metode ispitivanja zavarenih spojeva svornjaka prema zahtjevima norme HRN EN ISO 14555 ovisno o razini kvalitete, promjeru svornjaka i radnoj temperaturi. U eksperimentalnom dijelu rada prvotno su postupkom 783 zavarena dva tipa uzoraka svornjaka koja se sastoje od 12 zavarenih svornjaka promjera Ø22 mm i 12 zavarenih svornjaka promjera Ø19 mm, te su zatim na njima provedena ispitivanja definirana prema normi HRN EN ISO 14555 što uključuje vizualni pregled, test savijanja, makroanalizu i test vlačne čvrstoće. Kriteriji prihvatljivosti dobivenih rezultata ispitivanja definirani su prema normi HRN EN ISO 3834-2, te se daje analiza rezultata i procjena razine kvalitete zavarenih spojeva. Na kraju je određena prikladnost provedenih ispitivanja za primjenu ovih dvaju tipova zavarenih svornjaka u radnim uvjetima i za različite načine opterećenja.
Abstract (english)
The teoretical part of this thesis covers stud welding processes with detailed insight in stud arc welding using ceramic ferrule or shielding gas (process 783). Investigation methods of those welding joints according to HRN EN ISO 14555 standard in terms of quality levels, stud diameter and ambient temperature are also described in detail. In experimental part, two types of samples were welded using process 783. Samples were consisted of 12 welded studs of diameter Ø22 mm and 12 welded studs of diameter Ø19 mm. Therefore, they were investigated with visual examination, bend test, macro examination and tensile test according to HRN EN ISO 14555 standard. Furthermore, acceptance criteria was defined and analysis of results was carried out as well as evaluation of quality levels of welding joints according to HRN EN ISO 3834-2 standard. Finally, suitability of experiments done was defined for use in working ambient for both types of welded studs as well as their use with different types of stress.
