Abstract

Both types of industrial lasers, CO₂ and Nd:YAG, are used for welding with wide range of maximal power values. Successful results of laser welding depend on many different factors: energy, diameter, mode structure, polarization and focus position of laser beam; thickness, accurate positioning and gap of welded parts, kind of shielding gas. With LASAG Nd:YAG pulsed laser system KLS 246-102 we made optimization of welding parameters for different metals 0.5 mm thick and some types of the weld geometry. Our experimental results were used for welding of the side joint of the steel motor covers. These precious parts are used in automobile racing models. Finite elements model is used to predict a heat affected zone.
