Weldig of the different type of steel by the Yb-YAG laser
Chlád, Luboš ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
The master's thesis presents an experiment of welding of high strength steel Docol 1200 M and of steel DC01 by the fiber Yb-YAG laser. The experiment is based on testing welds which were made during the experiments. The lasers, laser technologies of welding, steels of higher strength, tailored blanks technology and testing of welds are described in the theoretical part. The practical part contains description and evaluation of tests of welds – transverse tension test, Vickers hardness test, Erichsen cupping test and macrostructure and microstructure test. The final evaluation results of the experiment are presented in the conclusion of the master's thesis.

Technology solution with cutting operation of "cover" component
Chlád, Luboš ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
In mentioned solution technology of cover part is processed component analysis, proposal of semi-finished product and production technology. In this thesis are selected concrete cutting machines, tools and technological process is elaborated. At the end the techno-economic evaluation is done. This evaluation deals with calculation of times for separate cutting operations, number of machines, tools and workers.
