Welding Processes: Techniques, Characteristics and Applications
Dr. Nakul Ramanna Sanjeevaiah
Abstract
Various industries depend on welding procedures to combine materials and build sturdy, dependable structures. The various welding techniques, their traits, and their applications are described in this chapter. The topic of welding and its importance in construction and production are introduced in the chapter's opening paragraph. The classification of welding techniques into the four major categories of fusion welding, solid-state welding, brazing, and soldering follows. Brief explanations of each category are provided, outlining the underlying ideas and methods used. Arc welding, gas welding, and resistance welding are a few of the frequently utilized techniques covered under fusion welding. The chapter explains each process' fundamental workings as well as the tools employed and significant applications. Additionally, solid-state welding techniques including friction welding, ultrasonic welding, and diffusion bonding are described, with an emphasis on how well-suited they are for attaching materials without melting. brazing and soldering are discussed further as methods for combining components with a filler substance that has a lower melting point. It describes how these two processes are similar and dissimilar, as well as how they are used in diverse sectors. The chapter also briefly discusses new developments in welding, such as laser welding and electron beam welding, while emphasizing their special benefits.
