Welding of the framework from aluminium alloys
Rašek, Ondřej ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
For TIG welding of transformer fame is important enough weld root fusion, however exposed surfaces must remain unaffected. Three types of test were made to determine properties of welds under different conditions. Tests were macroscopic inspection, tensile test and fracture test. Next was economic evaluation of different methods. Best results were for single layer weld with pre-heated material.

Surface casting defects
Rašek, Ondřej ; Pernica, Vítězslav (referee) ; Tomek, Ladislav (advisor)
Surface defects in casting include after decades of research on current problems of metal cast. They mean significant losses for foundries. Thesis includes a review of kinds of defects, their origins and their examinations, the effects on the mechanical properties and their machinability.
