Laser welding has evolved as an important industrial manufacturing process for joining a variety of metallic and nonmetallic materials. With the developments in the high-power laser technology over the past few decades, laser welding is now capable of joining thicker sections with higher processing speed and better weld quality. Due to the noncontact nature of laser processing, high degree of automation is possible providing economic advantages in the typical industrial environment. Even though, laser welding seems to be a simpler process, it presents significant challenges to produce defect-free welds at high speed and under reproducible conditions. This requires a strong understanding of the underlying concepts of laser–material interactions in the regime of laser welding conditions. Since extensive literature is published on the topic of laser welding in dedicated books, book chapters, and journals, this chapter is intended to present only brief discussions on important aspects of laser welding process.
