LASER TREATMENT INSTALLATION Russian patent published in 1998 - IPC

FIELD: mechanical engineering; welding; thermal treatment. SUBSTANCE: movable unit provided with drive 7 which moves it in horizontal plane is positioned above sheet 5 being treated. Drive actuating mechanisms may be in contact with sheet being treated or may not be in contact with the latter when drive is made as linear motor. Movable unit also has operating objective 9 with turning mirror 10 coupled to mirror of turning unit 3 either kinematically or optically or by means of electric drives of mirrors. Movable unit is supplied with electric power and operating gases either independently or by means of supply assembly and lines. Given construction does not use mechanical elements of drive and heavy moving assemblies. EFFECT: simplified construction, higher dynamic characteristics. 7 cl, 3 dwg
