Study on Characteristics of Inner Ring Laser Powder Feed Molten Pool of Thin Workpiece

Abstract:

Article Preview

In order to obtain the characteristic parameters of molten pool and realize real-time control of laser power, a high-speed CCD is used to monitor the laser rapid forming process of thin-walled rotating hollow cone, which is based on the technology of "hollow beam, powder tube center, inside-beam powder feeding".Experiments show that: In the plateau stage, pool area changes in 0.25mm2-0.7mm2, laser power remains at about 1kw, formed parts achieves maximum height of 55mm.
