Robot posture controlled electric arc deposition laser forging additive manufacturing method and equipment

Abstract

The invention discloses a robot posture controlled electric arc deposition laser forging additive manufacturing method and equipment for complex structural components. By adopting a robot posture control scheme, the space position of a melt forming part on a machining region can be freely adjusted, and the melting material flowing, falling and collapsing problems caused by the gravity action are solved. Meanwhile, the force effect of shock waves induced by pulse laser is used for reducing or eliminating internal defects and residual stress of a melting region and refining grains of the melting region, and the mechanical performance of the formed metal parts is improved. By means of the robot posture controlled electric arc deposition laser forging additive manufacturing method and equipment, the complex structural metal parts can be directly and rapidly formed, the efficiency is high, and the quality of the formed metal parts is relatively high.
