Unconventional Metals Hardsurfacing Technologies
 Krejčí, Vojtěch ; Šárka,, Šimůnková-Houdková (referee) ; Čelko, Ladislav (advisor)
The main objektive of the bachelor thesis is to evolve problems of metalic surface welding and to implement the basic partition of the most expanded used technologies of surface welding. Sometimes we can see the term deposition metalic surface welding too but in practice is used technical term metalic surface welding. The introdution includes the basic acquaintance with problems and the characterization of the proces of surface welding including the summary of its advantages and disadvantages. In other chapters we aim on individual technologies of surface welding, its principle and using in technical practice. Simultaneously is worked out the overview of already unused or minimally used technologies of surface welding. After the presentation of individual technologies follows the section dealing with partition of materials used for surface welding by the basic material as well as surface welding materials at the present technical practice. In the experimental section of thesis follows selected examples of using the presented technologies of surface welding in practice at present.

Tramway Shallow Crossing Preventive Maintenance by Surface Welding
 Křečková, Magdalena
The article deals with the issue of preventive welding and maintenance of tramway shallow crossing. The article presents the main influences the development of head loss and deformation of shallow crossing which are characterized by gradual loss of material and change in the geometry of grooves. The article presents a case study of a long-term monitored tramway shallow crossing in the locality od Prague - Vyton which demonstrates typical development of condition of grooves of tramway shallow in time to its preventive maintenance by welding and next development after maintenance and its comparison with the original geometry of new tramway shallow. The article presents also preventive maintenance by surface welding and reprofiling grooves during this preventive maintenance.
