| Abstract: |
| At present, additive manufacturing technology is mainly divided into laser additive manufacturing technology, electron beam additive manufacturing technology and wire and arc additive manufacturing technology. Compared with other additive manufacturing technologies and traditional machining methods, wire and arc additive manufacturing technology has advantages of fast forming speed, low cost, high availability of raw materials, uniform and chemical composition of formed parts, and excellent mechanical properties. Therefore, it is widely used in manufacturing of large metal parts, aerospace and other fields. Similarly, due to the diversification of wire and arc additive manufacturing, parts of different standards can be manufactured. So it has gradually become the mainstream part processing technology. This paper mainly introduced the additive manufacturing technology based on arc as heat source, such as consumable electrode gas shielded welding additive manufacturing technology, cold metal transition additive manufacturing technology, non consumable electrode gas shielded welding additive manufacturing technology, plasma additive manufacturing technology and multi energy field assisted arc additive manufacturing technology, including magnetic field arc, laser arc and electric field arc composite additive manufacturing technology. In manufacturing technologies without composite additive, the purpose of consumable electrode gas shielded welding was mainly to melt the welding wire with high heat concentration to achieve the purpose of additive. Although high heat input could ensure the continuous forming in the additive manufacturing process, there were also cracks in parts and components, resulting in the failure of parts and components. Therefore, the cold metal transition additive technology optimized from the GMAW technology could fully realize low heat input and additive to manufacture parts without welding slag spatter. The additive manufacturing technology of non consumable electrode gas shielded welding was an arc cladding process that produced metal agglomeration by heating metal through the arc between non consumable electrode and base metal. This technology could not only manufacture parts with excellent mechanical properties, but also solve the additive manufacturing problems of some refractory metals. Compared with additive manufacturing technologies of gas metal arc welding and gas tungsten arc welding additive manufacturing technology, the energy beam of plasma arc additive manufacturing technology was concentrated and could form more complex workpieces, but it was still limited to additive manufacturing of simple metals. In composite additive manufacturing technologies, the mutual superposition and combination between energy and energy beam was used, or a certain degree of external field assistance such as heat, force and magnetism was added, which could have a certain impact on the macro morphology, microstructure and forming accuracy of the formed parts, and finally improve the repair rate and mechanical properties of the parts. From the perspective of macro morphology, microstructure and mechanical properties, this paper analyzed the influence of process parameters or process characteristics on the macro morphology of additive manufacturing parts, discussed the microstructure evolution mechanism of additive manufacturing parts and its influence on mechanical properties, and put forward the problems and suggestions of single heat source and multi energy field assisted arc additive manufacturing technology at the present stage. |
