Abstract
Aluminium welding with laser is very difficult due to high optical reflectivity and substantial temperature difference between surface oxide layer and bulk aluminium. Problems are reflected in undisered and uncontrolled process dynamics. The aim of this research is to obtain informations about induced dynamics with developed optodynamic detection techniques. On the base of the results a laser source with two kinds of laser pulses will be developed. We assume that simultaneous use of few ms long laser pulse and few ns long laser pulse will enable stable oxide removal and enlarge stability and repeatability of the welding process. Study of the influence of two kinds of laser pulses on process dynamics will give informations on which optimal laser welding parametrs might be defined. Laser welding technique with simultaneous use of typically 5 ms long laser pulse with another few ns long Nd:YAG laser pulse has not been studied yet and it presents a novelty world wide.
