【 摘 要 】

To have a further study on the dynamic response characteristics of process parameters in cold metal transfer wire plus arc additive manufacturing(CMT-WAAM), the paper selects aluminium alloy 2319 as experimental material. On the basis of previous experiments, step response experiments were carried out for the forming parameters, welding speed(WS), wire feeding speed(WFS), arc length correction and pulse correction included. After WEDM, the width and height of the single layer single pass(SLSP) were captured respectively, and then the image processing algorithm was used in Halcon12.0 software for edge extraction and static extraction of sample contour's morphology features. In this paper, different feature extraction algorithms were proposed for the layer height and the pass width, and the characteristics of process parameters were given.
