The track components that are the most heavily loaded from the axles of train units are the switch components and rail crossing parts. These parts can be refurbished by welding on suitable types of additional materials. Parts made of high-alloyed Mn-steel (Hadfield steels) need to meet specific conditions for their welding. For the experiment, ESAB OK Tubrodur 14.71 and ESAB OK Tubrodur 15.65 materials were used. The results show the feasibility of appropriate procedures under specific conditions due to the occurrence of metallurgical defects affecting the safety of operation on railway and tram lines. The aim of the experiment was to perform and assess the properties of two types of austenitic welds of different chemical composition on the rail head and rail grooves with the same welding parameters.
