Abstract
The invention relates to a laser head () for connecting tubular parts () by the laser transmission method and to a method of connecting the tubular parts () by means of the laser head (). The laser head () and the method that can be performed by the laser head () are suitable in particular for connecting a connecting element or branching element () to one end of a plastic pipe (). The laser head () makes simultaneous welding possible and has at least two shell parts () that can be radially separated from each other so that the laser head () can be placed around a connecting section () or a connecting region () of the tubular parts (). A number of laser sources () are arranged in the shell parts () in such a way that the laser beams () emerging from the laser sources () overlap at the connecting section () or at the connecting region () of the parts ().
