Research on deposited layer scaning trace skanning based on rapid-prototpying using CMT technology

In additive manufacturing process using CMT welding process, research on the influence of specimen deformation in different welding path was made. And by using Dimensional Least-Squared Methods, a quantitative measure method of specimen deformation, called S-Judging law, was modeled. Compared the value of S in different welding path with the summarized characteristic that large deformation accompanied with a bigger value of S, the suitable welding trace planning principle was acquired and had succeeded in acquiring well-formed and dense-organized specimen during the real arc welding additive manufacturing process, which founded an experimental base in deposited layer scanning traces planning.
