Progress of welding in shipbuilding
Urban, Václav ; Kubíček, Jaroslav (referee) ; Kovář, Petr (advisor)
This work deals with the methods of welding in shipbuilding, summarises the basic techniques used for welding of the SAW, MAG, MIG, TIG, laser, Laser-Hybrid. It describes the properties of welded material. Especially the materials HY80 and HY100. It follows from the filler materials. In particular materials Spoolarc 95 and 120. Particular emphasis is placed on the method of Laser-Hybrid, its properties and use in shipbuilding. Finally, describes the method of welding aluminium using FSW, preparation of welded surfaces and producting of sandwich panels.

Filler materials for the fusion welding
Durajová, Věra ; Kovář, Petr (referee) ; Daněk, Ladislav (advisor)
The bachelor´s thesis elaborated in frame of bachelors studies branch B2341 deals the problematic filler material for fusion welding. On the basis belles - lettres problems technology welding and their filler material was shown it several kinds filler material for individual welding technology (MIG/MAG, hand arc welding, TIG, submerged-melt welding). First is mentioned problems rise fusing watering - place and on what principle individual technology work. After it are mentioned filler material (producer ESAB Vamberk) electrode, tubule, soft - centred tubule.

Material nonlinear static response of civil structures
Kinclová, Radka ; Vlk, Zbyněk (referee) ; Nevařil, Aleš (advisor)
The aim of this bachelor’s thesis is the non-linear elastic and plastic response of the simple beam structures. Also the problematics of the plastic hinges development is adressed. This thesis will then describe the origin and magnitude of the residual stresses caused by welding. Ideal elastic-plastic behavior of materials and elastic behavior with strenghtening will be used to determine the limit load capacity of the simple structures and will be compared to solution in the ANSYS software.

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.

Svařování hliníkových slitin wolframovou elektrodou
Hartman, Tomáš
This thesis focuses on undetachable endless connection by aluminum welding and its alloys by TIG methods. Detailed description of TGI welding method is included in the thesis. The second part deals with a detailed description of aluminum, aluminum alloys, problems that can occur in the process of welding, methods used for creating of undetachable endless connection by welding and conditions for creating of the connection of two parts. Theoretical part of the thesis focuses on comparing of the quality of new links between parts and renovated parts. Links undergo tensile test, metallographic examination, description of defects and evaluation of the quality of the link. The third part of the thesis focuses on safety and possible dangers from welding.
