This model has been developed using only a graphical user interface of a finite element commercial code and can be easily usable in industrial R&D environments. The model takes into account the three phases of the matter: the vaporized metal, the liquid phase, and the solid base. The liquid/vapor interface is tracked using the Level-Set method. To model the energy deposition, a new approach is proposed which consists of treating laser under its wave form by solving Maxwell's equations. All these physics are coupled and solved simultaneously in Comsol Multyphysics®. The simulations show keyhole oscillations and the formation of porosity. A comparison of melt pool shapes evolution calculated from the simulations and experimental macrographs shows good correlation. Finally, the results of a three-dimensional simulation of a laser welding process are presented. The well-known phenomenon of humping is clearly shown by the model.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380021394466289284","@type":"Researcher","foaf:name":[{"@value":"Mickael Courtois"}],"jpcoar:affiliationName":[{"@value":"ArcelorMittal Global R&D Montataire , F-60160 Montataire, France and , EA 4250, LIMATB, F-56100 Lorient, France"},{"@value":"University of Bretagne-Sud , F-60160 Montataire, France and , EA 4250, LIMATB, F-56100 Lorient, France"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021394466289283","@type":"Researcher","foaf:name":[{"@value":"Muriel Carin"}],"jpcoar:affiliationName":[{"@value":"University of Bretagne-Sud , EA 4250, LIMATB, F-56100 Lorient, France"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021394466289280","@type":"Researcher","foaf:name":[{"@value":"Philippe Le Masson"}],"jpcoar:affiliationName":[{"@value":"University of Bretagne-Sud , EA 4250, LIMATB, F-56100 Lorient, France"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021394466289282","@type":"Researcher","foaf:name":[{"@value":"Sadok Gaied"}],"jpcoar:affiliationName":[{"@value":"ArcelorMittal Global R&D Montataire , F-60160 Montataire, France"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021394466289281","@type":"Researcher","foaf:name":[{"@value":"Mikhaël Balabane"}],"jpcoar:affiliationName":[{"@value":"Institut Galilée Université Paris 13 , F-93430 Villetaneuse, France"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"1042346X"},{"@type":"EISSN","@value":"19381387"}],"prism:publicationName":[{"@value":"Journal of Laser Applications"}],"dc:publisher":[{"@value":"Laser Institute of America"}],"prism:publicationDate":"2014-07-08","prism:volume":"26","prism:number":"4"},"reviewed":"false","url":[{"@id":"https://pubs.aip.org/lia/jla/article-pdf/doi/10.2351/1.4886835/13280177/042001_1_online.pdf"}],"createdAt":"2014-07-09","modifiedAt":"2023-06-27","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390021525786504576","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Simulation on Keyhole Behavior and Pore Control in Pulsed Laser Induced Arc Welding Process of Magnesium Alloy"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.2351/1.4886835"},{"@type":"CROSSREF","@value":"10.2320/matertrans.mt-m2024105_references_DOI_Awd5M5xKHf9l2ylAKKh14l0rYGq"}]}
