Summary: | The invention discloses an electro-welding additive manufacturing method of nuclear power station SAP refrigerator end covers. The method herein comprises: I, conveying raw metal wires to the surfaceof a base via a conveying mechanism and an electro-welding head, allowing the raw metal wires and the base to generate electric arcs under overlaying protection of an aid so that part of the overlaying aid is melted into a molten slag bath; II, allowing current to pass through the raw metal wires and the molten slag bath to generate resistance heat and slag heat, melting the raw metal wires underthe thermal composite high-energy heat action of arc heat, the resistance heat and the slag heat so that a local bath is formed in the surface of the base; III, conveying the raw metal wires and the aid continuously, controlling the welding head to move by a computer according to hierarchical slicing data so that layerwise overlaying of the bath is performed on the base to obtain a finished product. The method herein has h |
