Study on dependency of the weld geometry on process parameters in laser hybrid welding of aluminum alloy
Wojnar, Michal ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
A study carried out in the bachelor 's degree in engineering technology deals with changes the geometry of the weld technologies created laserTIG . The theoretical part provides an overview of the basic characteristics and advantages of welding technology laserTIG a summary of the issues welding of aluminum alloys. The experimental part consists in the execution of fifteen test welds on a sheet of Al alloy 2024 tl . 3 mm. From the measured values of individual welds were prepared according to the depth and width of the seam TIG welding current at a constant laser power and dependence on a specific area of the weld heat input Qs. By comparing the dependencies have been demonstrated theoretical advantages of laser hybrid technology , which consist mainly of increasing the welding speed and lower heat load of the welded material. Using the laser hybrid welding for welding of aluminum alloys proven advantageous.

LaserHybrid utilization in welding and brazing
Labaj, Petr ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
LABAJ Petr: LaserHybrid utilization in welding and brazing The thesis deals with the basic knowledge of LaserHybrid welding, which is a combination of laser welding, and arc welding. There is also mentioned the use of shielding gas, which has a major impact on the entire welding process. Other part deals with the practical use of the welding method, it analyses the differences in diverse applications according to an industry sector, a type of used material and especially their advantages and disadvantages. LaserHybrid is a welding technology, which has a huge potential to cause a revolution in the field of welding. Its characteristics such as efficiency, quality and accuracy with which LaserHybrid systems operate are highly required. An example is the shipping industry, where was achieved a cut in production times and substantial positive economic outcome.

Analysis of welding by LASERHYBRID process
Teplý, Jan ; Hála, Michal (referee) ; Kovář, Petr (advisor)
The project is elaborated for the basic analysis of hybrid welding that combines laser welding with other welding methods, especially with the MIG and MAG technologies. Besides the Laserhybrid process the methods, of which this Laserhybrid welding is composed, are also presented here. These methods are compared considering the aspects: firstly their advantages or disadvantages, followed by the welding performance, the economic aspect or the application in mechanical engineering. The welding using the relatively new and so far not much widely used Laserhybrid method is very efficient especially for the weld jointing of various bodywork parts. Respectively, this method is efficient for its smaller molten pool, better gap bridging and also for its economic aspect to reduce production times.

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.
