Light collection system for the spectroscopic monitoring of orbital welding. The invention facilitates the capture of the light generated by the orbital welding process allowing its monitoring by means of sensor systems based on the analysis of the light radiation generated by the plasma. It consists of a section of bare optical fiber (4) wound on the inner face of the protection cup (3) that incorporates the welding gun. The fiber must have the opto-geometric characteristics necessary for the light incident on its cover to be captured and propagated by the nucleus, directing it to the remote analysis instrument. One end of the optical fiber can remain inside the bowl, being finished in a way that contributes to the capture of the light. The fundamental application of the invention focuses on the monitoring of welding processes by optical methods. (Machine-translation by Google Translate, not legally binding)

La invención facilita la captura de la luz generada por el proceso de soldadura orbital permitiendo su monitorización mediante sistemas sensores basados en el análisis de la radiación luminosa generada por el plasma. Consiste en un tramo de fibra óptica desnuda (4) enrollada sobre la cara interna de la cazoleta (3) de protección que incorpora la pistola de soldadura. La fibra deberá tener las características opto-geométricas necesarias para que la luz incidente en su cubierta sea capturada y propagada por el núcleo, dirigiéndola al instrumento remoto de análisis. Uno de los extremos de la fibra óptica puede permanece en el interior de la cazoleta, estando terminado de forma que contribuya la captura de la luz. La aplicación fundamental de la invención se centra en el monitorizado de procesos de soldadura mediante métodos ópticos.
