<p>The present invention relates to a cutting line marking device and a cutting line marking method using the same. According to the present invention, the cutting line marking device, capable of marking a circular or oval cutting line on an outer surface of a pipe, includes a support installed on the outer surface of the pipe through an attachment hole; a support shaft installed on the support; at least one horizontal shaft combined with a rotary shaft combined with an upper part of the support shaft; a laser combined with both ends of the horizontal shaft to emit a light source to a position of the outer surface of the pipe to be marked when the horizontal shaft rotates; and a distance measurer measuring a distance between the laser and the cutting line. The cutting line marking method, capable of marking an cutting line on an outer surface of a second pipe by using the cutting line marking device in order to connect an end of the second pipe to an outer surface of a first pipe, includes a step of collecting distance data by angle by marking the cutting line on the outer surface of the first pipe by using the cutting line marking device; a step of inputting the collected distance data by angle into a line carriage; a step of placing the line carriage on the outer surface of the second pipe; and a step of marking the cutting line on the outer surface of the second pipe according to the distance data by angle, collected at the collecting step, by operating the line carriage.</p> |
