Popis:	The observation on microstructure and microhardness has been evaluated by experimental methods and also approached to simulation work. One found out higher volume fraction of martensite inside the HAZ and the FZ that is the main cause of higher hardness insides these zones and no softening zone created by laser Nd: YAG on sheet metal of dual phase steel DP600. So the precaution during laser welding Nd: YAG at any welding speed, focal point position and power should be considered in order to prevent a crack and fracture of laser lap joint DP600 during service.
