Developments in modelling and simulation of laser and hybrid laser welding
S-J. Na and W-I. Cho, KAIST, Korea
Laser and hybrid welding processes involve very complex transport phenomena and thus rather limited modelling and simulation are available yet. With the advances in computing power and efficient computation techniques, however, it is expected that comprehensive modelling and simulation can be achieved and used to determine the optimal welding parameters resulting in minimum weld defects. This chapter presents the research trends and issues on modelling and simulation of laser and hybrid welding.
