Description

technical field [0001] The invention relates to the technical field of multi-heat source and multi-material additive manufacturing, in particular to a laser cladding-double-filament CMT arc wire powder composite additive manufacturing system for heterogeneous components. Background technique [0002] Additive manufacturing technology is a rapid prototyping technology based on the principle of discrete accumulation, driven by three-dimensional data of parts, using high-energy beams to connect powder or wire materials layer by layer by melting to manufacture solid parts. [0003] At present, metal additives are mainly based on laser, arc and electron beam heat source additives. Among them, due to the concentration of laser beam energy, laser additives have good stability in the additive process. After additives, the surface of the sample has good molding quality and high molding accuracy. However, due to the influence of laser power and high price, there are low additive effic...

Problems solved by technology

At present, such complex metal structures are mostly produced by additive manufacturing, but when adding complex multi-metal materials to compound high-performance large-scale heterogeneous components, a single heat source cannot meet its multi-material, high-precision and high-efficiency requirements, and often needs to use A variety of additive equipment, a variety of additive processes, and a variety of materials can only be completed by cooperating with each other, which requires higher technical requirements and a larger production space, which greatly reduces production efficiency and increases the cost of additive materials.

[0005] At present, there is no additive equipment that integrates multi-materials and multi-heat sources. In order to solve the problems of low efficiency, high cost, high technical requirements, and difficult operation of multi-metal materials composited with high-performance large-scale heterogeneous components, a new method is proposed.
