Reza Beygi is a postdoctoral researcher at the Institute of Mechanical Engineering and Industrial Management (INEGI). He obtained his PhD in the area of welding metallurgy at Sharif University of Technology in 2014. Since then, he has been working on welding metallurgy, procedure development, microstructural characterization, thermal analysis, and mechanical analysis of the welded structures.Eduardo A. S. Marques is a postdoctoral researcher at the Institute of Mechanical Engineering and Industrial Management (INEGI) and guest lecturer at the Department ofMechanical Engineering of the Faculty of Engineering of the University of Porto (FEUP).He obtained his PhD in the area of structural adhesive bonding for aerospace applications at FEUP in 2016 and now studies the effect of high strain rates, extreme temperature and high relative humidity on the behaviour of various materials and bonded structures.Lucas F. M. da Silva is Full Professor in the Department of Mechanical Engineering atthe Faculty of Engineering of the University of Porto (FEUP) and editor-in-chief of theJournal of Advanced Joining Processes. He leads the Advanced Joining Processes Unit (AJPU) of the Institute of Mechanical Engineering and Industrial Management (INEGI).
