Abstract

LE PROCEDE DE TRAITEMENT PAR LASER D'UNE PIECE EN ACIER 26 CONSISTE D'UNE PART A PROVOQUER UNE IRRADIATION DE FAISCEAUX LASER 16 SUR UN POINT A TRAITER DE LA PIECE D'ACIER, TOUT EN PROJETANT UN JET DE GAZ 32 COAXIALEMENT AUX FAISCEAUX LASER EN DIRECTION DE CE POINT A TRAITER, DE MANIERE A FORMER UN PLASMA 34 AUTOUR DU POINT A TRAITER. IL CONSISTE D'AUTRE PART A PROJETER EN DIRECTION DE CE POINT A TRAITER UN AUTRE JET DE GAZ 42 OBLIQUEMENT PAR RAPPORT A LA DIRECTION D'IRRADIATION DES FAISCEAUX LASER 16, DE FACON A APPLIQUER FORTEMENT LE PLASMA 34 CONTRE LA PIECE D'ACIER 26. UTILISATION POUR SOUDER, DECOUPER ET TREMPER DES PIECES EN ACIER.THE LASER TREATMENT PROCESS OF A STEEL PART 26 CONSISTS ON THE ONE HAND IN CAUSING IRRADIATION OF LASER BEAMS 16 ON A POINT TO BE TREATED OF THE STEEL PART, WHILE PROJECTING A JET OF GAS 32 COAXIALLY WITH THE LASER BEAMS TOWARDS THIS POINT TO BE TREATED, SO AS TO FORM A PLASMA 34 AROUND THE POINT TO BE TREATED. ON THE OTHER HAND, IT CONSISTS OF PROJECTING IN THE DIRECTION OF THIS POINT TO TREAT ANOTHER JET OF GAS 42 OBLIQUENTLY IN RELATION TO THE DIRECTION OF IRRADIATION OF THE LASER BEAMS 16, SO AS TO STRONGLY APPLY THE PLASMA 34 AGAINST THE STEEL PART 26 USE FOR WELDING, CUTTING AND TEMPERING STEEL PARTS.
