The method includes, before forming the cladding layer, acquiring a fluidity of the metal powder, and changing the laser output pattern according to the acquired fluidity.Type: GrantFiled: January 2, 2018Date of Patent: October 6, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hiroki Tateishi

Patent number: 10792766Abstract: The invention relates to additive manufacturing field and laser shock peening (LSP) field, in particular to a combined apparatus for layer-by-layer interactive additive manufacturing with laser thermal/mechanical effects. In the apparatus, a LSP module and a SLM module operate in alternate so as to perform LSP for the formed part in the forming process of the formed part, and thereby a better strengthening effect of the formed part is achieved. The invention effectively overcomes the challenges of “shape control” against deformation and cracking of the formed parts incurred by internal stress and “property control” against poor fatigue property of the formed parts incurred by metallurgical defects during additive manufacturing, improves fatigue strength and mechanical properties of the faulted parts, and realizes high-efficiency and high-quality holistic processing of the formed parts.Type: GrantFiled: June 8, 2017Date of Patent: October 6, 2020Assignee: JIANGSU UNIVERSITYInventors: Jinzhong Lu, Haifei Lu, Jianhua Yao, Kaiyu Luo, Fangnian Lang, Liujun Wu, Yikai Shao

Patent number: 10792767Abstract: A laser preheating control method is applied to a laser preheating control device. When a cutter processes a workpiece along a process path, a laser source of the device is provided to output a laser beam to the workpiece for selectively forming a laser spot on the workpiece surface. And according to a movement direction of the cutter, a laser controller of the device is provided to form the laser spot only on a preheating region of the workpiece, where in front of the cutter in the process path, for preheating the workpiece in the preheating region. As a result, the laser spot will not repeatedly heat the workpiece behind the cutter in the process path, and the qualitative change of the workpiece caused by repeating heating is preventable.Type: GrantFiled: December 26, 2017Date of Patent: October 6, 2020Assignees: Metal Industries Research & Development Centre, Parfaite Tool Co., Ltd.Inventors: Yu-Ting Lu, Yu-Fu Lin, Jui-Teng Chen, Wen-Long Chang, Chih-Hung Chou

Patent number: 10792771Abstract: Disclosed is a method of making an integrally bladed rotor. According to the method, a rotor disk comprising a radially outer rim surface is provided. A portion of the disk outer rim surface is removed, leaving a protrusion on the rotor disk outer rim surface. The disk with material removed is subjected to thermal processing. A blade comprising an airfoil and a base is positioned such that a base surface is in contact with the protrusion, and heat, pressure, and motion are applied between the blade and the disk to friction weld the base surface to the protrusion.Type: GrantFiled: September 12, 2017Date of Patent: October 6, 2020Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Michael F. Machinchick, Luke H. Rettberg, Andrew L. Haynes, Janet M. Stanley, Vasisht Venkatesh, David Ulrich Furrer, James R. Murdock, Daniel Gynther, Michael J. Linden
