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. 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 from the tunnel.

Abstract: The present invention provides a multi-fiber laser output system that delivers at least three fiber outputs arranged in a circumferential pattern or otherwise at least four distinct laser outputs from a single processing cable. The present invention allows for controlling the at least three laser modules and delivering their respective outputs in a pre-determined sequence in a single processing cable, thereby providing multiple processing steps on a work piece that heretofore required separate optics for each beam. The at least three laser outputs are optimized for use in creating spot welds, seam welds or virtual wobble welds when used for seam welding.
Abstract translation: 本发明提供了一种多光纤激光输出系统，其输出至少三个以圆周图案排列的光纤输出，或另外输送来自单个处理线缆的至少四个不同的激光输出。 本发明允许控制至少三个激光模块并且以预定的顺序在单个处理电缆中传送它们各自的输出，由此在工件上提供多个处理步骤，该处理步骤迄今为每个光束需要单独的光学器件。 当用于缝焊时，至少三个激光输出被优化用于创建点焊，缝焊或虚拟摆动焊接。

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.

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 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.
