Welds and joints of rails - manufacturing and maintenance

Završnim radom obradio sam temu zavara i spojeva tračnica – tehnologija izrade i održavanja. U prvom poglavlju rada opisani su osnovni problemi željezničke infrastrukture vezani uz tračničke spojeve. Zatim su dane osnovne informacije o tračnicama i prikazan njihov razvoj kroz povijest od XVII. st. pa sve do danas. U radu se zatim govori o spajanju tračnica s naglaskom na važnost kontinuirane zavarene tračnice. Prikazane su vrste tračničkih spojeva te se opisuju razni postupci njihova izvođenja. Isto tako opisuju se vrste održavanja željezničke infrastrukture te metode mjerenja stanja kojima se dolazi do optimalnog održavanja kvalitete kolosijeka. Također, opisana su ispitivanja koja se provode na sastavima tračnica kako bi se osigurala sigurnost i dostatna kvaliteta kolosijeka.In the final paper, I covered the topic of rail welds and joints - production and maintenance technology. In the first chapter of the work, the basic problems of railway infrastructure related to rail connections are described. Then basic information about the railways was given and their development through history from the 17th century until today. The paper then discusses the joining of rails with an emphasis on the importance of a continuous welded rail. The types of rail joints are presented and various procedures for their execution are described. It also describes the types of railway infrastructure maintenance and condition measurement methods used to achieve optimal track quality maintenance. Then describes the tests that are carried out on the rail joints in order to ensure the safety and sufficient quality of the track
