摘要

A process and assembly set up a laser beam emitter axis on one side and a process gas beam axis on the other. The laser beam processes work pieces e.g. sheet metal. An independent claim is also included for a laser cutting beam assembly that focuses the laser beam and gas beam at the cutting zone. The two beams are brought together progressively to meet at a convergence point at which point the axes are registered.
