Abstract:

This chapter first describes the history and current status of the laser welding technology. Then, fundamentals of laser welding, such as keyhole formation and collapse, laser-plasma interaction, weld pool dynamics, porosity formation mechanisms, metal melting and solidification, etc., are elaborated. Finally, new developments in laser welding such as hybrid laser-arc welding, multi-beam laser welding, electromagnetically assisted laser welding, and future challenges and development of laser welding are discussed.
