摘要：

Based on the inside-laser powder feeding technology, the forming research of close-packed multivariant twisty thin-wall parts is performed. The spatial motion trajectory and the pose of the cladding nozzle are obtained. According to the analytic relationship between the cladding layer section and the process parameters as well as the single-pass experiment, the height process model is set up and the forming of binary twisty thin-wall parts is performed. The close-packed multivariant twisty thin-wall parts are accumulated by the intermittent cladding process. The testing results show that the surface of formed parts is smooth, the minimum clearance among blade units is 6.5 mm, and the thickness of blades is mainly stable around 2.7 mm. The distributions of the microstructure and microhardness are relatively homogeneous. © 2017, Chinese Lasers Press. All right reserved.
