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.
