Welding of high strenght steel by laser
Číp, Tomáš ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
This project, elaborated within the engineering studies (code of field of study: N2301), presents experiment of welding of high-strength steel by laser. In this project, the samples of high-strength steel DOMEX 420MC will be welded by laser welding method and the welded joints will then be compared with welds made by MAG method. The theoretical part of this project summarizes the following key words in individual chapters: lasers, technology of welding of steel using laser, welding by MAG method, steel with higher strength, types of defects and check of welded joints. The practical part contains description of and assessment of mechanical tests of welded joints – weld bending test and transverse tension test. Further on, the tests of macrostructure and microstructure of welded joints were conducted and assessed. Final results of whole experiment are reviewed at the end of my diploma thesis.
