Design of wire feeder for TIG process
Kozumplík, Filip ; Slováček, Marek (referee) ; Kubíček, Jaroslav (advisor)
This thesis describes the design of a wire feeder for TIG welding, its drive and control electronics, capable of reacting to changes in welding parameters. First, different types of drives were compared and their suitability for the wire feeder was evaluated with regard to their regulation, precision, speed and torque. A stepper motor with a planetary gearbox was selected. Then, a shaft adaptor has been designed, coupling the gearbox to the wire feed. Based on strength calculations were obtained the requirements for mechanical properties of material for its production. An adaptor body from an aluminum alloy has been created, housing the shaft adaptor and to which the gearbox and wire feed are mounted. Also, the control Electronics have been designed. The control system is split into several boards, each fulfilling a specific purpose. A circuit has been developed, capable of a safe measurement of arc voltage and able to withstand the high frequency ignition pulse. In addition, a circuit for protection of the drive against said pulses, circuit for detecting contact between the filler wire and the workpiece, main control board with a microcontroller and a control panel have also been designed.

Comparison of cladding by the electron beam and plasma process
Rudyk, Martin ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
This diploma thesis deals with plasma cladding and electron beam cladding. The theoretical part is divided into several chapters which is focused on description of these methods of cladding process. In the practical part the particular experiment of electron beam cladding (EBC) and plasma cladding (PC) is described. In the conclusion overall results were assessed, both methods were compared each other and possible exploitation in industry was described.

Renovation of tools steels for cold forming
Hrabina, Martin ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
Master’s thesis “Revovation of tools steels for cold forming“ characterizes wear resistant welds for tool steels. The thesis is dividend into two main chapters. The first chapter of the thesis is focused on the theory of wear for cold work steels. The theory is combined with an experimental chapter. The experimental part describes particular materials and technology for welding. The conclusion of the thesis is evaluated results of test for mentioned technology and welding conditions.

Využití metody svařování v ochranné atmosféře aktivního plynu ve strojírenské praxi
Černý, Oldřich
The aim of this bachelor thesis is joining metals by welding, namely metal active gas welding. The first part is dedicated to different methods of welding in engineering practice and describes the best-known methods and principles in detail. The second part focuses on the selected welding process. It explains the principle of the method, metal transfer from the electrode to the parent material and describes the welding equipment used for this method. The final part deals with filler materials, active gases and parent materials used in practice.
