| description | 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 specif ic 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 fluctuatio ns 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 th e power of the light source such that desired melt pool properties are obtaine d. Subsequently the melt pool (7) solidifies. |
