Abstract: The superiority of the connection of nut with protection by laser welding is expounded.The method of laser welding is used to study the organize and performance of Q235 steel and H62 brass protective nut connected by laser welding respectively.Test results show that the formation of protective nut by laser welding have narrow heat affect zone and minimum organization grow up inclination,gentle hardness gradient,and the protective cover is nearly not out of shape
