Abstract

A laser cutting/welding installation including a laser head configured to deliver a laser beam and a cooling device for cooling the laser head is disclosed. The laser beam is designed to generate a hot spot on a workpiece by incidence thereon and form a solder bath from a portion of the workpiece affected by the hot spot. The cooling device includes a vortex tube with a compressed gas inlet supplied with a compressed gas, a cold gas outlet, and a hot gas outlet. The vortex tube cold gas outlet is plumbed directly to an interior volume of the laser head and configured to deliver a cold gas directly to the interior volume of the laser head for cooling thereof.
