Welding of finegrain steel from range of DOMEX steel by YbYAG fiber laser.
Němeček, Tomáš ; Daněk, Ladislav (referee) ; Mrňa, Libor (advisor)
The project elaborated within the engineering studies of the branch Manufacturing technology presents an experiment of welding of high strength steel by fiber laser. The project includes a theoretical study, which deals with the welding material properties, principles and types of lasers and laser welding technology. The practical part contains a verification of the welding parameters according to the standard ČSN EN ISO 15614-11. The final evaluation results of the experiment at the close of the project are presented.

Plasma welding of high-strenght steel
Šknouřilová, Eva ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis deals with plasma welding high strength steels. It divided into two parts, the theoretical part described the problems of method plasma welding and welding of high strength steels. In the experimental part of the many exams test the suitability of selected materials and parameters of the keyhole plasma welding. An assessment of the quality and mechanical properties of welded joints.

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.
