Influence of welding direction on depth of penetration for MAG method
Šmak, Radim ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
This bachelor thesis deals about Influence of welding direction on depth of penetration in S 235 JR steel for MAG welding. First theoretical part of the thesis was devoted to a description and technology of the chosen method. In the second practical patr of the thesis was designed optimal welding parameters and conditions of welding. Based on them was performed an experiment. From the experiment was detected the depth penetration, heat affected zone and structure of the metal.
Vliv tepelného zpracování na vybrané mechanické vlastnosti oceli
Šmak, Radim
This diploma thesis deals with methods of heat treatment of tool steel. The thesis briefly describes iron alloys and their properties, possible heat treatment is described. In the experimental part, there is hardening of K720 steel, (ČSN 41 9312) into various hardening environments is performed and mechanical properties such as hardness, impact work and steel strength are detected. The results evaluate the best heat treatment for blade production, both functional and ecological. According to the best method of heat treatment, the production of the product will be realized.
