Overview

Welding is the most important method of joining components made of metallic materials. Most welding processes involve the melting of the surfaces to be joined, followed by subsequent cooling. Melting is achieved by local heat input, keeping heat diffusion into the component and heat dissipation into the surroundings as low as possible. The effects of local heating are summarized under the term weldability , a property of the structure to be welded influenced by design, material and manufacturing measures. In recent years, theoretical developments in thermodynamics, continuum mechanics and microstructural kinetics have made a systematic assessment of weldability possible. This includes the weldability-related process. The systematic approach based on theory and mathematics is termed weldability analysis . This book is based on this systematic approach. It proceeds from the temperature field, treats residual stress and distortion on that basis and ends with practitioners' measures to reduce the former. A preliminary chapter introduces the fields and a final chapter reviews the strength effects of welding.
