Abstract

L'invention appartient au domaine de la technique du traitement thermique laser et lumineux de matériaux métalliques, de leurs alliages, d'aciers hautement résistants à capacité de trempage possédant des propriétés physiques différents et un raccord soudé non linéaire. Lors de l'utilisation de ce procédé on régule la vitesse de variation de la température dans la zone de soudage par le déplacement coordonnée du rayon laser et d'au moins un faisceau lumineux. On assure une forme elliptique des tâches du faisceau lumineux et du rayon laser, avec un rapport des dimensions des axes longitudinaux et transversaux des axes de l'ellipse dans la tâche compris entre 105 et 107 watt/cm2. Le procédé de soudage par laser et lumineux permet de fabriquer un raccord soudé de qualité; il peut s'utiliser en construction mécanique, dans l'industrie aérospatiale et dans le génie naval.
