Apparatus for cutting a pipe end for intersection with another surface comprising a horizontally positioned and movable boom, roller means to support and axially rotate a horizontal pipe parallel to the boom, a photocell scanner mounted on the boom and positioned to follow a template circumscribing a pipe on the roller means, drive means responsive to a signal from the photocell scanner, adapted to move the boom horizontally in either axial direction as the photocell scanner follows the template, and a cutting torch movably supported by a mounting on the boom and positioned to cut through a pipe, rotating axially on the roller means, in a cutting path having the same contour as the template. A method of cutting the end of a pipe for intersection with another surface, comprising placing the pipe on roller means to support and axially rotate it horizontally and parallel to a horizontally positioned and movable boom having a cutting torch movably supported by a mounting on the boom and a photocell scanner spaced from the torch, placing a template which is readable by the photocell scanner on and at least partially circumscribing the pipe, activating the roller means to rotate the pipe, and automatically moving the boom horizontally and axially responsive to the photocell scanner tracing the template and simultaneously cutting the pipe with the torch in a path which is controlled by the template.
