Advances in Welding Techniques for Similar and Dissimilar Materials

Introduction

Welding is one of essential part in manufacturing sector for assembling and make complete product. There are various conventional welding techniques exist and implemented successfully in manufacturing. Simultaneously, their modifications and advancements are increasing tremendously with accelerated commercial necessities. The modifications with conventional welding provide an excellent improvement in various factors of welding process such as improved welding strength, considerable reduction in cost, increasing productivity and ability to deal with various materials in manufacturing. Inventive ideas implementation with welding technology offers a new open up by various materials such as tough metals, composites, ceramics, non-metallic materials, similar and dissimilar materials. The main objective of this book chapter is given a preliminary knowledge of current innovations in the area of welding process along with its general concepts and distinct features of various techniques, assuming the common thoughtfulness of the researchers with respect to welding process. In last four decades, many welding techniques are evolved and practiced for the joining the metals by the researchers. Figure 1 represents the various welding techniques and its advancements practiced in industry. Advanced welding process can be classified into the three major categories such as fusion welding, non fusion welding and hybrid welding process.
