Background
Additive manufacturing techniques can be divided into two main categories, namely metal additive manufacturing and non-metal additive manufacturing, and for metal additive manufacturing, the categories can be classified from the types of raw materials and energy sources. The method can be divided into powder laying additive manufacturing, powder feeding additive manufacturing and wire feeding additive manufacturing according to different types of raw materials, and can be divided into three types of laser, electron beam and electric arc according to energy sources. The electric arc fuse wire additive manufacturing adopts a layer-by-layer surfacing mode to manufacture a compact metal solid component, and the electric arc is used as an energy-carrying beam, so that the heat input is high, the forming speed is high, and the electric arc fuse wire additive manufacturing method is suitable for low-cost, efficient and quick near-net forming of large-size complex components. The technology is widely regarded in the field of additive manufacturing by the advantages of unlimited size of a formed part, high forming speed, low cost and the like. However, most of the parts manufactured by the arc fuse additive manufacturing are based on the existing wire materials, and the manufacturing method has a great challenge for developing a novel alloy additive manufacturing large-scale component.

Meanwhile, the development of novel metal materials and preparation technology thereof also develops the market for the existing high-technology industry, so that the research of the novel metal materials is listed as the object of the primary development in all countries in the world. The novel alloy has excellent performance and special functions which are not possessed by the traditional materials, and the development of the novel alloy plays an important role in promoting key materials of high-tech industries. The development of novel metal materials mostly adds trace elements or strengthening phases to the components of the traditional alloy materials to change the alloy components or strengthen the alloy performance. For powder metal additive manufacturing, trace elements and strengthening phase powder can be added into an alloy powder system in a powder mixing mode, so that the aim of developing a novel alloy is fulfilled. However, it is difficult to add trace elements or strengthening phases to the conventional arc fuse additive manufacturing.

In the existing arc additive manufacturing technology, the change of the performance of the alloy by adding trace elements or strengthening phases in the manufacturing process cannot be realized. Therefore, in order to expand the application of the arc fuse additive manufacturing new alloys, improvements in the arc fuse additive manufacturing apparatus are required.
