Preface
Nowadays, it is usual define welding as “a materials joining process in which two
(or more) parts are coalesced at their contacting surfaces by the suitable application of heat and/or pressure.” Welding is a relatively new process, and it is normally
connected with metal parts, but the process is also used for plastics. Welding is
typically executed on parts made of same material, but some welding operations
can be used to join different materials. Weldability has been defined by American
Welding Society (AWS) as “the capacity of a metal to be welded under the fabrication conditions imposed into a specific, suitably designed structure and to perform
satisfactorily in intended service.” For this reason, an improvement of the technical
capability to predict the weldability is very important for the modern manufacturing
industry.
The purpose of this book is to present a collection of examples illustrating research
in welding technology with special emphasis in friction stir welding. Chapter 1 of the
book provides friction stir welding. Chapter 2 is dedicated to fundamentals of friction
stir welding, its application and advancements. Chapter 3 described modeling of
friction stir welding processes. Chapter 4 contains information on an application from
a defect—a friction stir channeling approach. Chapter 5 is dedicated to welding of
dissimilar metals—challenges and a way forward with friction stir welding. Chapter 6
provides microstructure and texture in welding—a case study on friction stir welding.
Chapter 7 is dedicated to tubular structures—welding difficulty and potential of
friction stir welding. Chapter 8 describes Industry 4.0 in welding. Chapter 9 contains
information on a comparative study of laser weldability of titanium alloys. Chapter 10
is dedicated to novel high-efficiency Keyhole tungsten inert gas (K-TIG) welding—
principles and practices. Chapter 11 provides fatigue analysis of dissimilar metal
welded joints of 316L stainless steel/Monel 400 alloy using GTAW. Finally, Chap. 12
is dedicated to industrial pipeline welding.
This book can be used as a research book for final undergraduate engineering
course or as a topic on manufacturing engineering at the postgraduate level. Also, this
book can serve as a useful reference for academics, researchers, mechanical, manufacturing, industrial and materials engineers, professionals in welding technology
and related industries. The interest of scientific in this book is evident for many
important centers of the research, laboratories and universities as well as industry.
