NONDESTRUCTIVE PENETRANT TESTING

Tema završnog rada je penetrantska kontrola ispitivanja bez razaranja. U uvodnom dijelu rada dana je osnovna podjela postupaka ispitivanja. Također je dan povijesni pregled razvoja nerazornih ispitivanja te su sistematizirane i ukratko objašnjene najčešće greške u materijalu. U nastavku rada opisane se osnovne metode kontrole bez razaranja. Budući da je tema penetrantska metoda, u centralnom dijelu rada detaljno je opisana ova metoda. Objašnjena su fizikalna načela ove metode te je opisan sam postupak ispitivanja. Također su opisana sredstva koja se koriste kao tekući penetranti. Na kraju rada dan je pregled ispitivanja koja se provode u praksi.The topic of the final thesis is the penetrant control of the test without destruction. The basic division of test procedures is given in the introductory part of this paper. A historical review of the development of non-destructive testing was also presented, and the most common material errors were systematized and briefly explained. In the continuation of the paper, the basic methods of control without destruction are described. Since the topic is a penetrant method, in the central part of the work this method is described in detail. The physical principles of this method are explained and the test procedure itself is described. Also, agents used as liquid penetrants are described in the paper. A review of the tests that are carried out in practice is given at the end of the thesis
