Abstract: Tamping is the technological operation of realizing a support of ballast under the inferior part of the sleeper, with the main purposes to assure a specific geometry and resistance of the railway and is being executed with the help of the tamping tools. The tamping tools work similarly as the cutting tools, with the difference that during the technologically tamping process doesn’t results splinters and the result is a support of ballast for the sleeper. Increasing the lastingness of the tamping tools is a primordial factor in the efficient exploitation, both technologically and economically. We have achieved for the first time in Romania, the first tamping tools having the active part plated with plates of metallic carbides through brazing.

 

Key words: tamping operation, tamping tools, lastingness, tine, metallic carbides.
