One of its variants, orbital friction stir welding, is of key importance in fundamental industries such as oil and gas and aerospace. For orbital friction stir welding, there is a need to develop not only new process parameters but also tools and ancillary mechanisms that can ensure sound, high-performing joints are obtained. This review assesses the current state of orbital friction stir welding, highlighting several key aspects related to this technology.<\/jats:p>","DOI":"10.3390\/met13061055","type":"journal-article","created":{"date-parts":[[2023,6,1]],"date-time":"2023-06-01T01:40:56Z","timestamp":1685583656000},"page":"1055","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A Review of Orbital Friction Stir Welding"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4330-5125","authenticated-orcid":false,"given":"Francisco B.","family":"Ferreira","sequence":"first","affiliation":[{"name":"UNIDEMI, Department of Mechanical and Industrial Engineering, School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1602-3317","authenticated-orcid":false,"given":"Igor","family":"Felice","sequence":"additional","affiliation":[{"name":"UNIDEMI, Department of Mechanical and Industrial Engineering, School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0024-6110","authenticated-orcid":false,"given":"Isaque","family":"Brito","sequence":"additional","affiliation":[{"name":"UNIDEMI, Department of Mechanical and Industrial Engineering, School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6906-1870","authenticated-orcid":false,"given":"Jo\u00e3o Pedro","family":"Oliveira","sequence":"additional","affiliation":[{"name":"CENIMAT|i3N, Department of Materials Science, School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9072-5010","authenticated-orcid":false,"given":"Telmo","family":"Santos","sequence":"additional","affiliation":[{"name":"UNIDEMI, Department of Mechanical and Industrial Engineering, School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"},{"name":"Laborat\u00f3rio Associado de Sistemas Inteligentes, LASI, 4800-058 Guimar\u00e3es, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,31]]},"reference":[{"key":"ref_1","unstructured":"Thomas, W.M.
