Numerical Simulations of Modern Joining Techniques Illustrated with Examples of the FSW and EBW Methods
Journal Title: Biuletyn Instytutu Spawalnictwa - Year 2017, Vol 61, Issue 5
Abstract
The article aims to present major advantages resulting from the use of tools for numerical analyses of modern welding processes, i.e. friction stir welding (FSW) and electron beam welding (EBW). The article presents basic issues related to the modelling of the FSW process, describes mechanisms to be taken into consideration in relation to numerical analyses of the above-named process and indicates problems which should be taken into account during the modelling of the EBW process. In addition, the article presents exemplary analyses of the FSW and EBW processes.
