| Abstract | For example in vehicle or crane production and in the steel construction area in many areas the weight reduction has a decisive influence on the development of new products. So modern, temperature-sensitive high-performance materials replace more and more unalloyed structural steels. The processing window by welding these materials is much smaller, so that the exact determination and compliance of the t8/5-value (cooling rate) is important. This is why the welding parameters and the exact determination of specific parameters have a great impact on the calculation and determination of the t8/5-value as well on the resulting mechanical and technological characteristics. Rezime Na primer, u proizvodnji vozila ili dizalica i području čeličnih konstrukcija u mnogim područjima smanjenje težine ima odlučujući uticaj na razvoj novih proizvoda. Tako moderni, temperaturnoosetljivi materijali visokih performansi zamenjuju sve više i više nelegirane konstrukcione čelike. Okvir obrade zavarivanjem ovih materijala je mnogo manji, tako da je tačno određivanje i usklađenost vrednosti t8/5 (brzina hlađenja) vrlo važno. To je razlog zašto parametri zavarivanja i tačno određivanje specifičnih parametara imaju veliki uticaj na proračun i određivanje vrednosti t8/5, kao i na rezultat mehaničkih i tehnoloških karakteristika. Depending on the welding process, a variety of welding parameters, welding seam geometry, the welding position and the layer structure changes the heat input into the component. On the one hand, the efficiency is changed and on the other hand they affect the cooling behavior by more than 60%. Various welding processes and parameters are analyzed as well different error potentials discussed and following their impact will be illustrated. Zavisno od postupka zavarivanja, različitosti parametara zavarivanja, geometrije šava, položaja zavarivanja i strukture sloja menja se unos toplote u komponentu. S jedne strane efikasnost se menja, a sa druge strane, oni utiču na vreme hlađenje za više od 60%. Analizirani su različiti postupci zavarivanja i parametri i diskutovane različite mogućnosti greške a njihov prateći uticaj će biti ilustrovan. The summation of the possible errors shows that the compliance with the mechanical and technological characteristics, as well as the theoretical determination of these values, and the calculation and simulation of the resulting sizes like arrears, microstructure or internal stresses is practically insufficiently possible. Knowing the sources of error and the use of this knowledge gained at the TU Chemnitz has a large contribution to improve the quality of welded joints. At the end recommendations of necessary adaptions of actual standards are visualised. Sabiranje mogućih grešaka pokazuje da je u skladu sa mehaničkim i tehnološkim karakteristikama kao i teorijskim određivanjem tih vrednosti a izračunavanje i simulacija rezultujućih veličina kao zaostataka mikrostrukture ili unutrašnjih napona je praktično nedovoljno moguće. Znajući izvore grešaka i korišćenje tog znanja stečenog na „TU Chemnitz“ ima veliki doprinos za poboljšanje kvaliteta zavarenih spojeva. Na kraju preporuke potrebne adaptacije stvarnih standarda postaju vidljive. |
