Publication number: 20220001490Abstract: A metal joiner system includes a power source and a metal joiner. The metal joiner includes a cleaning header, a cutting header, a joining header, and a joint finisher, each of which are communicatively coupled to the power source. The cutting header and cleaning header are configured to direct a first laser beam to prepare a joining region, and the joining header is configured to direct a second laser beam to form a joint in the joining region. A method of joining a metal substrates includes forming a joining region in abutting metal substrates, directing the first laser beam onto the joining region in a joint preparation stage, and directing the second laser beam onto the joining region to form a weld. A product of a metal joiner, a weld, has a portion of weld metal removed at the weld start and the weld crater regions.Type: ApplicationFiled: July 6, 2021Publication date: January 6, 2022Applicant: Novelis Inc.Inventors: Dechao Lin, Dewei Zhu, ChangOok Son, Kyle Haines, Louis Mitchell Nazro, Doug Keim, Curtis Eddie, Devesh Mathur, David Anthony Gaensbauer
