This book systematically describes the weld pool behavior in laser welding and its influencing factors from the perspectives of testing technology, theoretical calculation and process simulation technology, physical state transformation behavior of weld pools, and the impact of technical conditions on the weld pool behavior. The book covers extensive research achievements made in China in this field, some of which represent the latest cutting-edging researches conducted by the authors' research team. These latest research efforts mainly relate to the weld pool behavior of dual-beam laser welding, laser welding with filler wires, full-penetration laser welding of very-thick parts, and laser welding in vacuum and low vacuum conditions. The book is intended for undergraduate, graduate students and researchers who are interested in laser welding.

This book provides a systematic and comprehensive introduction to the technical principles, materials, processes, and equipment of the electron beam wire deposition technology (EBWD), while focusing on the research results of the author's scientific research team engaged in this technology in China. It mainly introduces the conceptual connotation, principle, and characteristics of the EBWD technology, its position and function in the additive manufacturing technology system, the direction and trend of technological development at home and abroad, the fundamentals and application results of the EBWD technology, including technical principles, equipment technology, special materials, manufacturing technology, quality testing, and application practices. So this book can serve as a reference book for teachers, students, and scientific researchers in scientific research institutions who are engaged in relevant studies.
