摘要:
In the context of additive manufacturing processes, the influence of specimen deformation from different welding paths is conducted by using CMT-AM. A least-squares method was used to quantitatively measure specimen deformation. The values of S (i.e., the sum of the distance from each feature point in a plane to the ideal plane)from different welding paths had significant influence on deformation of deposited layer.With the value of S increasing, the deformation of deposited layer gradually increased. With this result, a suitable welding trace plan was ascertained, which was successfully used to acquire well-formed and densely organized specimens during the arc-welding additive manufacturing process. Our results provide a foundation for experiments based on deposited layer scanning trace planning.
