Issues of the LaserHybrid welding method
Znášik, Samuel ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
The thesis deals with the issue of using LaserHybrid welding for the energy industry where the combination of laser and arc could facilitate higher quality welds resistant to aggressive environments, corrosion and oxidation. The methods that the hybrid process produce as well as possible replacements for the MIG and MAG methods are explored, as well as the different configurations and their possible impact on the process. The possible use of the technology for hyperbaric welding is also presented. The experimental part is devoted to the welding of refractory martensitic steel used in the power industry for the production of steam turbines. Weld structures at different parameters were investigated and hardnesses were compared.
