"A Non-autoregressive Dynamic Model based Welding Parameter Planning Me" by Zhihu Li, Zhimin Hou et al.
Wire and arc additive manufacturing(WAAM) is a promising method for directly manufacturing parts with complex shapes. However, the accuracy of the existing welding parameter planning methods would dramatically decrease when bead geometry changes dynamically due to the long-term dependence, strong coupling, and hysteresis properties of the WAAM process. To this end, a non-autoregressive(NAR) dynamic model is proposed to predict the bead geometry, and an adaptive model predictive control(aMPC) method is proposed to plan welding parameters to achieve high manufacturing accuracy. First, in the pro...
