Abstract

PURPOSE: To apply working such as welding and cutting without rotating the pipe work by rotating the rotating device which induction-reflects laser light from a generator by a reflecting mirror, about the pipe work thereby focusing and projecting the laser light to the outside circumferential edge of the pipe.
CONSTITUTION: The working device provided with a laser light generator 8, motor 9, reflecting mirrors 12, 14 and parabolic reflecting mirror 15 is mounted to the difficult-to-rotate pipe work 5 to be subjected to working sucn as welding and cutting. The cylindrical body 4 provided with plural reflecting mirrors is rotated by driving a motor 9 to reflect the laser light 13 from the laser light generator 8 by the reflecting mirrors 12, 17. The laser light is then focused on the surface of the pipe work 5 by the parabolic reflecting mirror 15 and is subsequently projected to the circumference of the pipe 5, whereby the working such as welding and cutting is applied. Even if the work 5 cannot be rotated, it may be readily worked by the laser light by rotatively radiating the laser light.
