Welding Basics

Welding is a fabrication or sculptural process that involves joining materials such as thermoplastics and metals together. During the joining process, heat is applied to melt the parts being welded together. The subsequent cooling of these melted parts results in fusion, creating a strong bond between the materials. Gas flame, electron beam, electric arc, and laser are the different sources of energy that can be used for welding. Arc welding is a type of welding that utilizes electric current to sustain an electric arc between the base material and an electrode, thereby melting the metal at the welding point. Gas tungsten arc welding and gas metal arc welding are the subtypes of arc welding. This book is a compilation of chapters that discuss the most vital concepts in the field of welding. Different approaches and methodologies have been included in it. This textbook is meant for students who are looking for an elaborate reference text about the subject.
