Improved aiming of a fine jet of fluid in a laser beam welding, machining or recharging installation by incorporating the laser beam in the fluid flow channel

摘要

The invention concerns the aiming of a fine jet of fluid from a blowing nozzle (5) onto a zone or object. The nozzle incorporates an ejection channel (10) including a terminal part (11) with an essentially circular section, and a luminous source (3) arranged in the axis of the ejection channel generating a non divergent mono- or poly-chromatic luminous beam, of which at least one wavelength is between 400 and 760 nanometers, coaxial to the ejection channel. The flow of the fluid is momentarily interrupted, by displacement of the zone or object, the luminous beam is aimed on the zone or object and the fine jet of fluid is projected onto the zone or object. Independent claims are also included for: (a) an aiming device for putting this method into service; (b) a welding, machining or recharging installation incorporating this aiming device. The luminous source is a laser source (claimed).
