Microstructure stability of electron beam welds
Rončák, Ján ; Havlík, Petr (referee) ; Jan, Vít (advisor)
The aim of this bachelor thesis is an evaluation of microstructure and functionality of welded joints by using methods of material engineering. At first, there are various methods of welding described in the theoretical part. In the second part, the thesis introduces every material that is used to create a welded joint. The final part then offers an explanation of every method used to analyse the process of welding. The joints were created on two specimens without any filler material and at the machine that uses electron beam. The first joint is a combination of austenitic hadfield steel with ferrite-perlite carbon steel and in the second case combined with stainless ferritic steel with high amount of chromium.
