Preface
ix
This book consists of 9 chapters, which systematically describe the weld pool
behavior during laser welding and its influencing factors, including the experimental
research, 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 research achievements of this field in China are intensively
reflected in the research results, some of which present the latest frontier research
work of the authors’ research team, such as the weld pool behavior of dual-beam
laser welding, the weld pool behavior of laser welding with filler wires, and the weld
pool behavior of heavy-thickness full-penetration laser welding and laser welding
in vacuum and low vacuum conditions, etc. Those who participated in compilation
of this book are Shuili Gong, Shengyong Pang, Hong Wang, and Linjie Zhang,
among which Shuili Gong is responsible for the content of preface and Chapter 1,
Shengyong Pang for the content of Chaps. 3–5 and Chaps. 7–9, Hong Wang for
the content of Chap. 2, and Linjie Zhang for the content of Chap. 6. The whole
book was reviewed and finalized by Shuili Gong. This book not only can be used
for reference for engineering technicians, scientific researchers in the field of laser
material processing, scientific researchers majored in material science, and teachers
and students in colleges and universities, but also have high reference value for
research and development personnel in the field of laser equipment, optical scientific
researchers, scientific and technical personnel in the related fields of laser application
physics, and teachers and students in colleges and universities.
During the compilation of this book, we received great support and help from
our research team. We would like to thank National Defense Science and Technology Key Laboratory of High Energy Beam Processing Technology in Beijing
Aviation Manufacturing and Engineering Institute, Huazhong University of Science
and Technology, Xi’an Jiaotong University and Taiyuan University of Science and
Technology, and especially thank Professor Jianxun Zhang of Xi’an Jiaotong University for his guidance for this book, Professor Jianzhong Xiao and Professor Jianxin
Zhou of Huazhong University of Science and Technology for their strong support
for this book, and our colleagues’ support and help. We would like to thank the
authors listed in the bibliography of this book for their works and papers which have
contributed greatly to the compilation of this book.
We’d like to comfort Professor Lunji Hu and Professor Liliang Chen of Huazhong
University of Science and Technology with this book. Without their support and
guidance over the years, the authors may not have completed this book.
Due to the authors’ limited knowledge, it is inevitable that there are inadequacies
and shortcomings in the book. You are welcome to criticize and correct us.
