abstract = "The aim of this study was to investigate the possibility to
use the industrial explosive Amonex, which belongs to a
group of low-to-middle detonation velocity explosives, for
welding of metallic materials. It consists of ammonium
nitrate and TNT as energetic components and other inert
ingredients and has a powdery consistency, easily applicable in a desirable layer over the metal plates to be welded.
Within this research, Amonex was applied to weld plates of
aluminium Al 2024 and steel 1.0216 (according to EN
10027-2). The procedure of welding was carried out in the
configuration of parallel plates, and afterwards the welded
joint was examined. Ultrasonic method and infrared imaging were used as non-destructive techniques, and then the
samples were cut from the welded plate using water-jet, in
order to perform microscopic analyses of the cross-section
in the joint area. It was observed that a good-quality welded
joint was obtained, and that the selected explosive may find
further application in this area. However, certain nonwelded area was observed, encouraging future modification
of the welding procedure set-up., Cilj ove studije je ispitivanje mogućnosti upotrebe industrijskog eksploziva Amonex, koji pripada grupi eksploziva
male-do-srednje brzine detonacije, za zavarivanje metalnih
materijala. Ovaj eksploziv se sastoji od amonijum nitrata i
TNT-a kao energetskih komponenti i drugih inertnih sastojaka, ima praškastu strukturu i lako se nanosi u željenom
sloju preko metalnih ploča koje se zavaruju. U okviru ovog
istraživanja, Amonex je primenjen na zavarenim pločama
aluminijuma Al 2024 i čelika 1.0216 (oznake prema EN
10027-2). Postupak zavarivanja izveden je na paralelno
postavljenim pločama, nakon čega je izvršen pregled zavarenog spoja. Kao metode IBR korišćene su ultrazvučna
metoda i termovizijsko ispitivanje. Primenom vodenog mlaza
iz zavarene ploče su isečeni uzorci u cilju ispitivanja mikrostrukture poprečnog preseka zavarenog spoja. Uočeno je
da je dobijen kvalitetan zavareni spoj, te da odabrani
eksploziv može naći dalju primenu u ovoj oblasti. Međutim,
takođe su uočene i određene površine nezavarenog područja,
što je nametnulo potrebu za izmenama postavke ovog
postupka zavarivanja.",
