This study explored the processing of single beads composed of ISO HS 6-5-2 high-speed steel (HSS) using the multi-beam laser melting method and a modified multi-beam laser focusing technique. Especially, the effects of multi-beam laser focusing position and laser power on rapidly solidified microstructure and temperature variation of the ISO HS 6-5-2 HSS during the laser melting process were investigated.
