This chapter describes carbon dioxide laser (CO2 laser) welding. Some types of CO2 lasers and special features of CO2 lasers are introduced in the first sections. Laser welding phenomena, which include the interaction of the laser beam with materials and gases, keyhole behaviour, formation mechanism and prevention of weld defects, are also described. Finally, some practical applications of CO2 laser welding are introduced.
