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.

Multibeam laser system and methods for welding

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.
