    Abstract: The present invention provides a fiber laser system that delivers from a single processing cable a multibeam output. The present invention allows for controlling multiple fiber laser modules and delivering their respective outputs in a pre-determined sequence but in a single processing cable, thereby providing multiple processing steps on a work piece that heretofore required separate optics for each beam. Custom fiber laser systems that combine processing steps tailored for a specific industrial application such as pre-heating, cutting, cleaning, welding, brazing, ablating, annealing, cooling, polishing and the like can be readily provided because of the present invention.

    Abstract: Una pistola de soldadura láser desplazable manualmente está configurada con una columna de soporte alargada que se extiende a lo largo de un eje longitudinal y está hecha a partir de material de peso ligero. Una placa de soporte está montada de manera desplazable en la columna mientras soporta sobre la misma un cabezal óptico que está provisto de una óptica de guía de rayos. La óptica está configurada para dirigir un rayo láser a lo largo de una trayectoria hacia una zona de soldadura a través de una ventana de protección del cabezal óptico. La pistola de soldadura láser también está estructurada con un primer brazo montado en la placa de soporte y que se extiende a lo largo de un eje longitudinal de la pistola diametralmente opuesto al cabezal óptico. La superficie interna del brazo desplazable tiene una superficie interna que define un túnel que está alineado con el cabezal óptico y axialmente atravesado por el rayo láser, una primera corriente que fluye axialmente de medio gaseoso presurizado, y una segunda corriente que fluye axialmente de medio gaseoso. La segunda corriente, que entra en el túnel a una presión menor que la de la primera corriente en respuesta a un gradiente de presión generado en la columna, no genera vórtices dentro de la columna. La primera y segunda corrientes salen a través del extremo aguas abajo del túnel a continuación de la zona de soldadura. Cuando las corrientes fluyen al exterior, retiran los residuos de soldadura que fluyen dentro del túnel antes de que los residuos alcancen la ventana de protección del cabezal óptico.

    Abstract: A hand displaceable laser welding gun is configured with an elongated support column extending along a longitudinal axis and made from lightweight material. A support plate is displaceably mounted to the column while supporting thereon an optical head which is provided with beam-guiding optics. The optics is configured to direct a laser beam along a path towards a welding zone through a protective window of the optical head. The laser welding gun further is structured with a first arm mounted to the support plate and extending along a longitudinal axis of the gun diametrically opposite to the optical head. The inner surface of the displaceable arm has an inner surface defining a tunnel which is aligned with the optical head and axially traversed by the laser beam, a first axially flowing stream of pressurized gaseous medium, and a second axially flowing stream of gaseous medium. The second stream, entering the tunnel at a pressure lower than that one of the first stream in response to a pressure gradient generated in the column, does not generate vortexes within the column. The first and second streams exit through the downstream end of the tunnel next to the welding zone. As the streams flow out, they carry out welding debris flowing within the tunnel before the debris reach the protective window of the optical head.

    Abstract: A robotically operated laser seam stepper is configured with an elongated support column extending along a longitudinal axis and made from lightweight material. A support plate is displaceably mounted to the column while supporting thereon an optical head which is provided with optics. The optics is configured to direct a laser beam along a path towards a welding zone through a protective window of the optical head. The laser seam stepper further is structured with a first arm mounted to the support plate and extending along a longitudinal axis of the stepper diametrically opposite to the optical head. The inner surface of the displaceable arm defines a tunnel which is aligned with the optical head and axially traversed by the laser beam, a first axially flowing stream of pressurized gaseous medium, and by a second axially flowing stream of gaseous medium. The second stream, entering the tunnel at a pressure lower than that one of the first stream in response to a pressure gradient generated in the column, does not generate vortexes within the column.
