Welding is a cost-effective and flexible method of fabricating large structures, but drawbacks such as residual stress, distortion and buckling must be overcome in order to optimize structural performance. Minimization of welding distortion and buckling provides a systematic overview of the methods of minimizing distortion and buckling in welded structures.

Following an introductory chapter, part one focuses on understanding welding stress and distortion, with chapters on such topics as computational welding mechanics, modelling the effect of phase transformations on welding stress and distortion and using computationally efficient reduced-solution methods to understand welding distortion. Part two covers different methods of minimizing welding distortion. Chapters discuss methods such as differential heating for minimizing distortion in welded stiffeners, dynamic thermal tensioning, reverse-side heating and ways of minimizing buckling such as weld cooling and hybrid laser arc welding.

With its distinguished editor and international team of contributors, Minimization of welding distortion and buckling is an essential reference for all welders and engineers involved in fabrication of metal end-products, as well as those in industry and academia with a research interest in the area.

Michaleris, Pan
Dr. Michaleris received his Ph.D. from the University of Illinois at Urbana-Champaign. He was employed as a senior research engineer with Edison Welding Institute for three years before joining the Department of Mechanical Engineering at Penn State University as an assistant professor. He has served as the Associate Editor of the Journal of Science and Technology in Welding, as well as being a principal reviewer for the Welding Journal. Most recently, he started a company, Pan Computing, soley dedicated to the development of physics-based modeling of additive processes. In early 2016 Pan Computing was acquired by Autodesk.
