This chapter describes the state of the art as well as the future trends of fast laser beam deflection and shaping for welding applications. The key principles of fast laser beam manipulation like galvanometer-driven and conventionally-driven mirrors are introduced. The beam movement over the workpiece as the first purpose and beam shaping as the second purpose are discussed in detail and explained by means of welding examples. Finally, an outlook for future trends and forthcoming requirements for the beam scanning equipment is given.
