Abstract
Zavarivanje je postupak spajanja dva ili više dijelova s ili bez dodatnog materijala u cilju dobivanja nerastavljivog spoja. Svaki zavareni spoj sastoji se od zone taljenja (ZT) i zone utjecaja topline (ZUT). Zavarivanje nije moguće bez unosa energije što uzrokuje promjene u samom zavaru i u zonama oko njega. Izuzetno je bitno da je spoj što jednoličnije kvalitete po svim presjecima (mehanička svojstva, udarna radnja loma, otpornost na trošenje itd.). Veliku ulogu kod zavarivanja ima ljudski... More faktor. S obzirom na to da ljudi nisu roboti gotovo je nemoguće da se ne pojave nepravilnosti tijekom rada. Nepravilnosti koje se mogu pojaviti prilikom zavarivanja izvedenog taljenjem prema normi HRN EN ISO 6520-1:2007 su:  100 – pukotine  200 – šupljine i poroznosti  300 – čvrsti uključci  400 – naljepljivanje i nedovoljni provar  500 – pogreške oblika  600 – ostale pogreške. [1] Svaka nepravilnost u zavarenom spoju je vrlo opasna i može dovesti do velikih nezgoda ako se na vrijeme ne otkrije i sanira. Iste je moguće otkriti razornim ispitivanjima (DT) ili nerazornim ispitivanjima (NDT). U praktičnom dijelu ovog rada opisan je način izrade dvije različite konstrukcije na kojima su primijenje neke od metoda nerazornih ispitivanja (vizualna, penetrantska i magnetska kontrola). Less
Abstract (english)
Welding is the process of connecting two or more parts with or without additional material in order to obtain an inseparable joint. Each welded joint consists of a melting zone (ZT) and a heat affected zone (HAZ). Welding is not possible without heat input which causes changes in the weld itself and in the zones around it. It is extremely important that the joint be of uniform quality in all sections (mechanical properties, impact fracture, wear resistance, etc.). The human factor plays a... More big role in welding. Given that humans are not robots, it is almost impossible not to detect irregularities during work. Irregularities that may occur during welding performed by melting according to EN ISO 6520:2007 are: •100 – cracks •200 – cavities •300 – solid inclusions •400 – lack of fusion and penetration •500 – imperfect shape and dimensions •600 – miscellaneous imperfections. [1] Any imperfection in a welded joint is very dangerous and can lead to major accidents if not detected and repaired in time. The same can be detected by destructive test (DT) or non-destructive test (NDT). The practical part of this work describes the way two different products are made on which some of the methods of non-destructive testing (visual, penetrating, and magnetic control) are applied. Less
