AB  - U radu je prikazana nova tehnologija aluminotermijskog zavarivanja (AT) prelaznih šina 49E1 na 60E1(EN 13674-1:2005.), oslonjena na potpuno nove materijale. Ona se odnosi na pešćane kalupe kod kojih su oblik i dimenzije ulivnog sistema projektovani tako da mogu odgovoriti svim zahtevima za postizanje zavarenih spojeva zadatog kvaliteta. Da bi ovaj zahtev bio u potpunosti ispunjen, projektovana je, takođe, AT smeša, čijom se aktivacijom dobija termitni čelik za ispunu, sa temperaturom izlivanja koja obezbeđuje optimalnu livkost metala, kao i viskoznost troske. U radu su zatim prikazani rezultati ispitivanja probnih prelaznih zavarenih spojeva, shodno standardima JŽS.Z2.610 i EN 14730-1:2012, a odnose se na utvrđivanje mehaničkih svojstava zavarenih spojeva, makrostruktirnih i mikrostrukturnih karakteristika, homogenosti i hemijskog sastava termitnog čelika za ispunu. Dobijeni rezultati pokazuju da je primenjena tehnologija optimalna, jer obezbeđuje upotrebu ove tehnologije u industrijskim uslovima na železnici.
AB  - The paper presents a new aluminothermic (AT) welding technology of 49E1 transition rails on 60E1 (EN 13674-1: 2005), based on entirely new materials. It refers to sand molds in which the shape and dimensions of the inflow system are designed to meet all requirements for achieving welded joints of a given quality. The AT mixture was also designed to fulfill those requests; resulting liquid steel has a casting temperature that ensures optimal castability of the metal and slag viscosity. The paper presents the test results of the transients welded joints, following the standards JŽS.Z2.610 and EN 14730-1: 2012, and relates to the determination of mechanical properties of welded joints macrostructural and microstructural characteristics, homogeneity, and chemical composition of thermite steel. The obtained results show that the applied technology is optimal because it ensures the use of this technology in industrial conditions on the railway.

AB  - Aluminothermic welding of rail is still a unique method for joining the rails because of its flexibilityand ease of performance, both during the reconstruction and construction of a new track, as well asin the ongoing maintenance of the continuity of the track. Although this procedure is applying foralmost hundred years with constant improvements, it still has serious shortcomings. Theshortcomings primarily relate to quality variability, which directly dependent on the training of theoperator and their compliance with the prescribed instructions and procedures, during the weldingprocess. The most common working mistakes are very similar to the casting failures that occur duringthe usual casting of steel. The process is susceptible because the welded joint is in constant straincondition caused by the structural differences between primary material and filler material (thermitesteel). This paper presents some working failures on the samples from the track in exploitation, aswell as the analysis of the causes of their formation. Also, the innovative way of performingaluminum welding of the rail was shown, which minimizes working mistakes and prevents workingfailures. The results of the quality testing of welded joints are done according to the EU standards.They pointed out that the implementation of this procedure provides greater safety of rail transportas well as its coherence because it significantly reduces the impact of faults of welding teams.

AB  - The developing of the universal tool for testing of tensile properties of hexagonal steel wire mesh for civil engineering is described in this paper. The developed tool allows repeated testing of hexagonal steel wire mesh of different dimensions without tool changes and is generally related with the procedure for the determination of tensile strength properties of different wire meshes. The construction of the tool which is related to the aims of the decreased mass consumption and high operation safety is described in detail. Particular attention is focused on the safety component of the tool which ensuring safety testing by preventing slipping of the wire mesh samples during loading. The paper also presents the Finite Element Analysis performed in order to verify the high safety factor of the developed tool. The contact regions with stress concentration behavior are analyzed by non-linear solvers. The obtained results and conclusion about the possible contributions of the developed universal tool for extensively testing of wire meshes for civil engineering are discussed.
