Claims

[Claims for Utility Model Registration] 1. A ring-shaped rotating body 1 through which the welded pipe P can penetrate through its center and which is provided at the pipe discharge position of the pipe making device 7, and a ring-shaped rotating body 1 that is held by the ring-shaped rotating body 1. a laser oscillator 2 and a ring-shaped rotating body 1
A cutting nozzle 4, which is fixedly installed at each of the laser oscillators 2 and which reflects the laser beam L from the laser oscillator 2 with a reflecting mirror 3 and focuses it on the surface of the welded pipe P, and a cutting nozzle 4 that is fixedly installed on the ring-shaped rotating body 1 at a constant speed. It is characterized by being composed of a rotating driving body 5, and a moving device 6 that moves this driving body 5 and the ring-shaped rotating body 1 in the direction of discharging the welded pipe P at the same speed as the pipe discharging speed. Laser cutting equipment for welded pipes. 2 Two ring-shaped rotating bodies 1 are provided at a pipe discharge position with a certain interval and rotate in synchronization with each other, and a laser oscillator 2 is held by these two ring-shaped rotating bodies 1. The welded pipe laser cutting device according to claim 1.
