abstract = "Explosively welded metal plates of large surfaces or specific geometries are used in equipment for
the production of electricity from renewable sources. In explosive welding, the energy of a
controlled detonation is used to create a joint, when one metal part collides with another at high
speed forming a weavy bonded interface. Explosive welding is used in the production of specialized
components for renewable energy sources, such as parts of wind farms or turbines, because enables
strong and secure connections between different types of metal or material. This technique can also
be applied in the production of specific components for solar industry, such as solar panel supports
that require strong and reliable connections, often between dissimilar materials that are difficult to
weld with conventional methods. In addition, explosive welding can be useful in the production of
batteries for renewable energy storage, where it is crucial to ensure that the connections are
mechanical and electrically reliable. For such structures it is important to be able to perform in situ
monitoring using nondestructive techniques to check the success of the performed welding on the
whole pieces or products made this way. This work considers the application of non-destructive and
destructive techniques to examine the quality of explosively welded joints of two different sets of
metal plates: aluminum alloy-steel and carbon steel- highly wear resistant alloy steel, with two
explosives, Amonex and Demex. Inspection of the joints was carried out using surface methods and
non-destructive volumetric methods. The following techniques were applied: visual method, liquid
penetrant testing, X-ray and ultrasound defectoscopy. To confirm the results of non-destructive
techniques, a microstructural analysis of the cross-section of the welded joint was performed. The
application of non-destructive testing techniques in testing the quality of explosively welded joints
contributes to the reduction of costs that would be caused by destructive tests, since these
techniques can be used to monitor the success of the process itself and thus improve the
technological process of producing bimetallic joints by explosive welding., Eksplozivno zavarene metalne ploče velikih površina ili specifične geometrije nalaze primenu u
opremi za proizvodnju električne energije iz obnovljivih izvora. U eksplozivnom zavarivanju koristi
se energija kontrolisane detonacije da bi se ostvario spoj, kada se jedan metalni deo sudara sa
drugim velikom brzinom formirajući spoj talasastog profila. Eksplozivno zavarivanje se koristi u
proizvodnji specijalnih komponenti za obnovljive izvore energije, kao što su delovi vetroelektrana
ili turbina, jer omogućava čvrste i sigurne spojeve između različitih vrsta metala. Ova tehnika se
može primeniti i u izradi specifičnih komponenti za solarnu industriju, kao što su nosači solarnih
panela koji zahtevaju snažne i pouzdane veze, neretko između raznorodnih materijala koje je teško
zavariti konvencionalnim postupcima. Osim toga, eksplozivno zavarivanje može biti korisno u
proizvodnji baterija za skladištenje obnovljive energije, gde je ključno osigurati da su spojevi
mehanički i električki pouzdani. Za primenu u takvim konstrukcijama važno je da se može vršiti in
situ kontrola primenom nedestruktivnih tehnika kako bi se proverila uspešnost izvršenog
zavarivanja celih komada ili proizvoda dobijenih na ovaj način. U ovom radu prikazana je primena
nedestruktivnih i destruktivnih tehnika za ispitivanje kvaliteta eksplozivno zavarenih spojeva dva
različita seta metalnih ploča: aluminijumska legura-čelik i ugljenični čelik-alatni čelik, sa dva
eksploziva, Amonex i Demex. Ispitivanje kvaliteta ostvarenih spojeva vršeno je površinskim
metodama i zapreminskim metodama bez razaranja i sa razaranjem. Primenjene su sledeće tehnike
bez razaranja: vizuelna metoda, ispitivanje tečnim penetrantima, radiografija i ultrazvučno
ispitivanje. Kako bi se rezultati nedestruktivnih tehnika potvrdili, izvšena je i mikrostrukturna
analiza poprečnog preseka zavarenog spoja. Primena tehnika ispitivanja bez razaranja u
ispitivanju kvaliteta eksplozivno zavarenih spojeva doprinosi smanjenju troškova kada se vrše
destruktivna ispitivanja. Ovim tehnikama može pratiti uspešnost samog procesa i na taj način
poboljšati tehnološki proces izrade bimetalnih spojeva eksplozivnim zavarivanjem.",
