Patent

CA 2476290

It is disclosed a method for controlled remelting of or laser metal forming on the surface (5) of an article (1). A light source and a signal capturing apparatus (15) is moved over the article (1). The light source with a specific power is used to melt the surface (5) of the article (1) locally and to form a melt pool (7). Thereby an optical signal (13) is captured by the signal capturing apparatus from the melt pool (7), and the monitored optical signal (13) is used for the determination of temperature and temperature fluctuations as properties of the melt pool (7). Furthermore, a control system (16) with a feedback circuit is used to adjust at least one process parameter such as the power of the light source such that desired melt pool properties are obtained. Subsequently the melt pool (7) solidifies.

L'invention concerne un procédé de refusion ou de formage de métaux au laser commandés sur la surface (5) d'un article (1). Une source de lumière et un appareil de capture de signal sont déplacés sur l'article (1). La source de lumière ayant une puissance spécifique est utilisée pour faire fusionner la surface (5) de l'article (1) localement et pour former un bain de fusion (7). Ainsi un signal optique (13) est capturé par l'appareil de capture (5) de signal provenant du bain de fusion (7), et le signal optique contrôlé (16) est utilisé pour la détermination de la température ainsi que des fluctuations de température en tant que propriétés du bain de fusion (7). De plus, un système de commande (16) à circuit de retour est utilisé pour régler au moins un paramètre de traitement tel que la puissance de la source de lumière, de manière à obtenir les propriété voulues de bain de fusion. Ensuite, le bain de fusion (7) se solidifie.
