Hamid Eisazadeh Old Dominion University

visit author page

Dr. Eisazadeh joined Old Dominion University (ODU) in Fall 2018. Before joining ODU, he was a faculty member at the County College of Morris for one year, and a faculty member at the Chabahar Maritime University over four years. Dr. Eisazadeh received his Ph.D. (2017) in Mechanical Engineering from Clarkson University in New York, his MSc (2005) in Manufacturing Engineering from Tehran University, and his BS in Manufacturing Engineering from Mazandaran University. He has several years of research and teaching experience, and he is a member of American Welding Society.

His work involves studying residual stress formation in dissimilar weld and additive manufacturing using finite element modeling and neutron diffraction measurement. He has examined and practiced various modern techniques to mitigate weld residual stresses and their consequences. Through his work, he has presented at several conferences and co-authored papers on the reduction of residual stress in dissimilar weld.

Abstract

Recent trends in the industry have led to an increased need for engineers with welding training. Not many universities in the U.S.A. offer welding courses at the undergraduate level. Engineers that do not receive education about this complex process, sometimes make very costly and dangerous mistakes. A more profound understanding of the welding process that expands beyond the basic comprehension of technology use is needed for the advanced manufacturing sector. Welding related courses need to include the complex interplay of the four states of matter (solid, liquid, gas and plasma), as governed by the laws of physics, with topics such as material science, phase diagrams, phase transformation, heat treatment, and possible failure modes of welds and working with special alloys and material that are difficult to weld. This paper will present two such courses at two different universities, both offered in mechanical engineering technology programs. These courses cover various welding processes, heat flow, residual stress, design, problems, codes, standards, and most importantly metallography.
