The invention concerns a method for pointing a fine fluid jet onto a zone or an object in particular in welding, machining, or laser hardfacing, the jet being emitted from a blowing nozzle (5), the nozzle comprising an exhaust channel (10) including a terminal portion (11) of substantially circular cross-section having a diameter not greater than 5 mm, a light source (3) arranged in the axis of the discharge channel (10) upstream of the nozzle (5) in the flow direction of the fluid flux, generating a non-divergent mono-or polychromatic light beam whereof at least one wavelength ranges between 400 and 760 nanometers, coaxial with the exhaust channel (10) and propagated inside the channel in the flow direction of the fluid, whereby, the fluid flow being momentarily interrupted, by relative displacement of the object or zone or the light beam, the light beam is pointed on the object or the zone and the fine fluid jet is projected onto the zone or object.
Procédé de pointage d'un jet fin de fluide sur une zone ou un objet notamment en soudage, usinage, ou rechargement LASER, le jet étant émis à partir d'une buse de soufflage (5), la buse comportant un canal d'éjection (10) comprenant une partie terminale (11) de section sensiblement circulaire de diamètre inférieur ou égal à 5 mm, une source lumineuse (3) disposée dans l'axe du canal d'éjection (10) en amont de la buse (5) dans le sens de l'écoulement du flux du fluide, générant un faisceau lumineux non divergent mono ou poly- chromatique, dont au moins une longueur d'onde est comprise entre 400 et 760 nanomètres, coaxial au canal d'éjection (10) et se propageant à l'intérieur du canal dans le sens d'écoulement du fluide, selon lequel, l'écoulement du fluide étant momentanément interrompu, en déplaçant relativement l'objet ou la zone ou le faisceau lumineux, on pointe le faisceau lumineux sur l'objet ou la zone et on envoie le jet fin de fluide sur la zone ou l'objet.
