About the book
This textbook will explore welding processes and the advances that have been made in welding technology over the last two decades. These processes include tungsten inert gas welding (TIG), shielded metal arc welded (SMAW), MIG, PAW, etc., and the advances that have been made in these areas. Given the high temperatures used in many welding processes, significant microstructural changes often occur in the materials to be joined. The metallurgy of welded joints and their properties will be studied to categorize the various regions formed at the joint during the welding processes where metals of similar composition and properties are joined. The type of defect formed during welding processes is quantified and reported.
Finally, the book will also discuss the properties of welded joints when advanced alloys such as aluminum, magnesium, titanium, stainless steel are joined using the available welding technology. The available welding equipment and technology have been repurposed for additive manufacturing, particularly wire arc additive manufacturing and additive manufacturing by friction stir welding.
