To overcome the problem of part forming effect and surface quality in surfacing metal forming

the size model of single and multiple weld was established

the relationship between the welds was analyzed

and the optimum deposition distance was determined. At the same time

the orthogonal experiment was used to analyze the influence of the welding parameters on the forming dimension

and the universality of the model was verified. In the example

through the design of the composite milling system

changing the forming path

the forming size was effectively controlled

and the feasibility and effectiveness of the process were verified.
