Developments in twin-beam laser welding technology

Y. Miyashita,     Nagaoka University of Technology, Japan

Abstract:

In this chapter the phenomenon, mechanism and method of twin-beam laser irradiation are introduced. Welding, including dissimilar materials welding, surface modification and cutting of a brittle material, are shown as particular applications of twin-beam laser welding. The advantages and effects of the technique are described. An analytical study on the convection behavior occurring during twin-beam laser irradiation is also shown as an example of using a numerical approach to understand the mechanism of twin-beam laser welding.
