Abstract. Results of experiments in hardening of threaded tube coupling with the use of ytterbium fiber laser are presented. The samples made from steel 38G2S type are used in the experiments. The treatment conditions, images of threaded parts microslices, as well as results of the wear resistance tests with the samples are demonstrated.
