Influence of welding parameters on a transverse distortion
Harmaniak, Daniel ; Vaněk, Mojmír (referee) ; Daněk, Ladislav (advisor)
In my bachelor thesis is described a theory of internal tensions and distortions during welding. My thesis also contains technological and structural principals used to minimalize them and methods used for elimination of internal tensions. There are also included calculated methods depending on the different parameters of welding concerning transverse distortions. A butt weld was done between two sheets of tin and its transverse shrinkage was measured. The measured value was compared with the calculated one.

The production of the console deburring machines
Hlavinka, Martin ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis submitted deals with the project of the change of the production of the semi-finished product of the console which is produced by casting from the cast iron ČSN 42 2420. The component forms the frame of the deburring machine with two electric motors with the gearbox. For the suggested production the method MAG of technology welding was chosen. Because of the given technology the new construction of the component was chosen. The welded product consists of eight parts burnt from heavy-walled sheet metals. The suggested material of the construction is steel S235JR and for welding the filler rod Weld G3Si1, diameter 1 mm is chosen. For the determination of the optimal parameters of welding the testing through the slap next to the skin weld (size a5) was made. Simultaneously with the testing the fracture areas and the weld root were examined. The suggested parameters of welding were used during the preparation of WPS. For the assembling of the component the operating schedule of welding is planned.
