This book, Welding - Materials, Fabrication Processes, and Industry 5. 0, presents an overview of various state-of-the-art manufacturing processes and innovative application materials. During conventional manufacturing processes, especially during joining, the materials' physical, microstructural, and mechanical properties deteriorate due to temperature extremes, severe plastic deformation, inappropriate processing parameters, and so on. Nowadays, advanced manufacturing processes and the latest grade of materials are playing a significant role in improving product quality as well as saving time and money in delivering the product to the customer. This book discusses advanced manufacturing processes and the latest grade of materials for innovative products.
