Abstract
Glavni zadatak završnog rada opisivanje je ispitivanja zavarenih spojeva metodama bez razaranja koje su česte u primjeni tj. ultrazvučno, vizualno, radiografsko, magnetsko te ispitivanje tekućim penetrantima. Detaljno su opisane karakteristične greške u zavarenim spojevima koje su uobičajene kod zavarivanja. Takve karakteristične greške su poroznost, čvrsti uključci, naljepljivanje, nedovoljni provar, pogreške oblika te pukotine. Svakoj navedenoj grešci treba pridodati određenu razinu pozornosti kako ne bi prerasla u grešku koja može uzrokovati otkazivanje zavarenog spoja. Opisane su prednosti i nedostatci pojedinih metoda bez razaranja kao i koju metodu treba koristiti kada se vizualnom kontrolom prepozna indikacija za grešku. U zadnjem poglavlju praktičnog dijela zadatka napravljeno je ispitivanje magnetskom metodom kontinuiranim magnetiziranjem koja se dijeli na tehniku fluorescentnim magnetskim česticama i obojenim magnetskim česticama na atestnoj ploči koja je zavarena po danim preporukama čišćenja osnovnog materijala i zavarivanja po tehnološkim propisima.
Abstract (english)
The main task of the final work was to describe the testing of welded joints by nondestructive methods that are common in application, ie. ultrasound, visual, liquid penetrants, radiographic and magnetic testing. The characteristic defects in welded joints that are common in welding are then described in detail. Such characteristic defect are porosity, solid inclusions, gluing, insufficient penetration, incorrect shapes and cracks that are considered unacceptablce welding defects and they are described as cold and hot cracks. The advantages and disadvantages of certain non-destructive methods are describd, as well as which method should be used when recognizing the error indication by visual control. In the last chapter of practical part of the task. A non-destructive magnetic test by continous magnetization is made, which we classify as flourescent magnetic particles and colored magnetic particles on the example of plates welded according to the recommendations of cleaning the base material and welding according to technological regulations.
