<p>The present invention relates to a method to cut a plasma arc of a nonferrous pipe using a water screen. The configuration of the present invention comprises: (S10) a preparing step of preparing the nonferrous pipe to be rotated by a rotational device; (S20) a cutting position selecting step of positioning the plasma arc of a plasma cutter to be projected onto a cutting position of the nonferrous pipe mounted on the rotational device; (S30) a water injection unit inserting step of positioning a water injection unit inside the nonferrous pipe; (S40) a cutting step of forming a water screen on the inner circumferential surface of the nonferrous pipe by spraying water to the inner circumferential surface of the nonferrous pipe onto which the plasma arc is projected through the water injection unit; and (S50) a collecting step of collecting the cut nonferrous pipe and the water injection unit.</p> |
