Comparison of the welding productivity MAG and FCAW
Kutil, Petr ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
This thesis is focused on arc welding with MAG and FCAW methods. The first part contains a brief description of these technologies. Emphasis is laid on the principle of arc welding in active shielding gas and on additional materials, especially on solid and flux-cored tubular wires. The second, experimental part, centres on the comparison of MAG (135) and FCAW (136 and 138) methods in terms of the productivity, costs and, last but not least, the quality of fillet welds made in PF welding position. Based on the calculated and measured figures obtained from the experiment, the most suitable method for the given welding position was chosen.

Study of weld plasticity of deep-drawn sheets welded by Laser-TIG technology
Kutil, Petr ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
This thesis is focused on laser welding and hybrid laser-TIG welding. The first part contains a brief theoretical description of these technologies. Standard quality and plasticity tests of welded joint are also mentioned. The second, experimental part, centres on the study of plasticity of tailored blanks (made of different types of HSLA steel), that are welded with laser and laser-TIG technology. The aim of the thesis is to assess process parameters effect on weld suitability for following deep drawning operation. Based on the calculated and measured figures obtained from the experiment, the most suitable welding parameters were chosen.
