METHOD OF GAS LASER CUTTING Russian patent published in 1994 - IPC

Abstract RU 2025244 C1

FIELD: manufacturing process with use of laser. SUBSTANCE: method comprises steps of directing at an initial time moment to a cutting zone a short-wave laser beam, then coaxially with it directing a circular beam of a long-wave laser with simultaneous supply of an active gas, controlling intensity value of irradiation power in dependance upon a ratio of power values and diameters of beam focal spots. EFFECT: enhanced efficiency. 2 cl, 1 dwg
