AbstractIn this study, many operations carried out by traversing laser beam on 6 mm thick S960 steel plates for various laser welding speeds and powers in order to determine influence of welding speed and power on penetration, shape of fusion zone and heat affected zone. A 16 kW Ytterbium fibre laser and pure argon as shielding gas were used in this experimental study. Data was evaluated and compared with some previous studies. Furthermore, an empirical formula between heat input and weld bead width was developed from results.
