Analysis of plasma cutting
Hauzarová, Michaela ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
Method of cutting material by plasma is constantly evolving and increasingly used technology. Plasma is used from small manual cutting devices to smart fully automated system. This technological study describes the technological principle of plasma cutting, properties of plasma in comparison with the other most common methods of material separation systems and presents CompleXX, the global program using m3 plasma system.

Welding of bicycle frame from titanium alloy
Richter, Tomáš ; Kandus, Bohumil (referee) ; Kubíček, Jaroslav (advisor)
This bachelor’s thesis is focused to titanium bicycle frame welding. The first part is about bycicle itself. It containes kinds of bikes, materials used for frames and influency of some proportions to handling properties. Next chapter is about titanium. There are properties of titanium and titanium alloys used for bike frames in this chapter. After that there is a chapter about TIG welding, which is mostly used for titanium. This method is mentioned both generally and concretely for titanium. Final part is about technology of bike frame building.

Surface treatment of car body
Talafa, Michal ; Kandus, Bohumil (referee) ; Kubíček, Jaroslav (advisor)
In this work, the theory describes modifications to the car bodies, especially their finishes. Thus pretreatment before the coating lacquer layers. There are described the types of pre-treatment such as degreasing and corrosion protection. Also deals with the coating, and their functions and applications to the car body. Since the body does not consist only of metal, there is another part of the work focused on the plastics that are used and their painting.

Repair of car body
Tolkner, Josef ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
The work deals with the issue of repairing the car following a minor accident, or his body and especially her painting. Bachelor's thesis has been designed to help inexperienced drivers to fix their cars with minimal cost and to yourself. At first, I deal with the profitability of their own work-if not paid the car repair due to its condition and price compared with estimated costs of repair and time consuming work performed. I describe a variety of work such as removing damaged parts, metal straightening, filling inequalities, grinding, coating layers of paint and assembly. At the end make the final calculation of the cost of repairs, time allocation, the result of labor-cost estimate for repairing the vehicle and compare all the costs estimated at the beginning.
