Title:
METHOD FOR LASER WELDING BY VIBRATING OR ROTATING LASER BEAM
Document Type and Number:
WIPO Patent Application WO/2020/076002
Kind Code:
A1
Abstract:
The present invention is a method for laser welding by vibrating a laser beam which is focused on a welding seam in a steel product seam welding, the method comprising: a condenser lens transmitting step of focusing a laser beam by irradiating the laser beam on a condenser lens; a reflector irradiating step of irradiating the laser beam, which has been focused by means of the condenser les transmitting step, on a first reflector provided on a first galvanometer; and a first axis galvanometer vibrating step of welding by vibrating the laser beam, which has been irradiated by means of the reflector irradiating step, by means of the first galvanometer, and irradiating the laser beam, which is reflected from the first reflector, while adjusting the amplitude by a predetermined angle or an angle perpendicular to the welding seam, wherein the first axis galvanometer vibrating step is performed by means of a control algorithm relating to the input, storage and execution of drive data for driving the vibration of the first galvanometer vibration.
