The invention relates to a heterogeneous thick-wall part edge sealing type additive manufacturing method. The additive manufacturing method comprises the steps that a model is obtained, an internal structure of the model is set according to performance of an additive manufacturing model, and materials used in different areas are rationally distributed; model slicing is conducted, specifically, model data of each layer is analyzed and calculated, and a required additive manufacturing process is rationally arranged as required; additive manufacturing preparation is conducted, specifically, according to the required additive manufacturing process, a type and a specification of a base plate and required consumables are selected, and a plasma arc additive manufacturing gun, a CMT additive manufacturing gun and a pouring gate are installed on corresponding robots; a program is generated, a model contour is extracted, an additive manufacturing path is planned, optimal process parameters are set for matching, and a corresponding program is generated and imported into a corresponding robot control system; and additive manufacturing is started, specifically, additive manufacturing is started in sequence according to a planned additive manufacturing gun path and a planned pouring gate path. According to the method, plasma arc additive manufacturing, CMT additive manufacturing and pouring manufacturing are combined, a large heterogeneous thick-wall component with high performance can be obtained, forming is good, and efficiency is high.
Description
technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to an edge-sealing and high-efficiency additive method for heterogeneous and heterogeneous thick-walled parts. Background technique [0002] Heterogeneous heterogeneous thick-walled components often have better performance than ordinary thick-walled components, such as the layered structure interwoven with soft and hard has higher strength, and the honeycomb structure has better toughness. This structure is complex and the material Numerous heterogeneous and heterogeneous thick-walled components are commonly processed by additive methods. In the process of metal addition, arc addition is more efficient than laser addition and electron beam addition. Plasma arc is a common arc addition. Since it is a non-melting electrode arc, the energy of wire and arc can be independently controlled. In this way, a thin layer, well-formed, and high-quality additive component can be ...
