The properties of welding joint after hot-dip galvanizing
Vítek, Pavel ; Suchánková, Ivana (referee) ; Kubíček, Jaroslav (advisor)
The project elaborated in frame of Master's studies branch 2303T002 presents a study of welded joints for hot-dip galvanizing. On the basis of literature study it is assumed that zinc influences the properties of welded joints. Samples were made of high strength steels DOMEX and wear-resistant steels HARDOX which were welded using MAG. Subsequently, half of the samples treated with zinc. The evaluation is used tear test and test Vickers hardness. Finally, the project is the comparison of the measured values of galvanized steel and steel without zinc.

Welding of fuel filters
Průža, Štěpán ; Suchánková, Ivana (referee) ; Kubíček, Jaroslav (advisor)
PRŮŽA Štěpán: Welding of fuel filters. This project, worked out in within engineering studies, branch M2307 – 02 Manufacturing technology, submits suggestions for decreasing of scrap during production – mechanized welding of fuel filters made out of aluminum EN AW – Al 99,5 using WIG/TIG methods. The theory is focused on arc welding issue. Verification of possible influences on the weld joints was tested during following experiments: top cover misalignment against the body of the filter, top cover deformation, gas flow, welding parameters setup, welding area purity, mechanization propositions. Evaluations of experiments – recommendation for elimination and prevention of bad quality weld joints. Key words: Welding, aluminum EN AW – AL 99,5, WIG/TIG method, weld’s joints defects, experiment, evaluation.
