A two dimension value simulation was carried out for studying the electromagnetic force effect on melting pool in plasma powder deposition process. As the process is a layer-laminated deposition process, the gravity and the fluid motion of molten metal in melting pool during the layer-laminated deposition process without supporting, it will difficult to form complex shape parts. So a new scheme which using the magnetic field to restrict the melting metal flow was proposed. The method designed a restricted equipment of magnetic field in order to prevent and reduce the fluid flow and collapse of the melting pool. Compared with traditional method, as the height of the deposition shape increased, the process restricted with electromagnetic force can make the shape of parts more complex and more accurate. The changes of the electromagnetic force field were simulated with the finite element analysis, while the effects of electromagnetic force on forming process were discussed. Simulation show that the method is feasible and practicable. The electromagnetic force will decrease the post-treatment procedure and could contribute to the process of plasma powder deposition manufacture.
