Study on Technics in Laser Accumulation of Change-Diametral Rotary Parts with the Coaxial Inside-Beam Powder Feeding

Abstract:

Based on the forming technology of "hollow laser beam and internal powder, adopting a novel device with coaxial inside-beam and internal powder feeding, the accumulation experiments of the change-diametral rotary parts are carried out on the substrate of 45# steel. This study is focused on the control of the parts inclination angle, Z axis incremental and laser power on the forming characteristics of the parts. The results show that with the Coaxial Inside-beam Powder Feeding Accumulation, the quality of molding parts that this experiment gets finally is higher with smooth appearance and lower roughness. The grain is fine and the microstructure distribute uniformly from bottom to top of forming parts.
