| description | A method for repairing defects on a structure is disclosed herein. The method comprises use of an additive manufacturing head to inject a flowable filler material into the defect. In certain embodiments, the additive manufacturing head can be a laser metal deposition (LMD) head comprising a powder nozzle and a laser. The structure can be, e.g., a pipeline or a pressure vessel used in petroleum, petrochemical, or natural gas applications.
L'invention concerne un procédé de réparation de défauts sur une structure. Le procédé comprend l'utilisation d'une tête de fabrication additive pour injecter un matériau de charge fluide dans le défaut. Dans certains modes de réalisation, la tête de fabrication additive peut être une tête de dépôt de métal par laser (LMD) comprenant une buse de poudre et un laser. La structure peut être, par exemple, un pipeline ou un récipient sous pression utilisé dans des applications de pétrole, de pétrochimie ou de gaz naturel. |
