Physical processes in fusion welding

Abstract

In recent years, major advances have taken place in our understanding of welding processes and welded materials. Because of the complexity of fusion welding processes, solution of many important contemporary problems in fusion welding requires an interdisciplinary approach. Current problems and issues in fusion welding are reviewed. Solution of these problems, apart from being a contribution to the advancement of science, is also necessary for science-based tailoring of composition, structure, and properties of the welded materials.
