The apparatus includes a pair of rotatable headstocks which are spaced apart. A side beam extends along at least a portion of the distance between the headstocks with the side beam being substantially parallel to a line connecting the centers of rotation of the headstock. The headstocks are respectively of a configuration to securely receive an end of a first one of a plurality of cylindrical workpieces. Support means is provided for rotatably supporting the plurality of cylindrical workpieces in end-to-end manner with the longitudinal axes thereof being substantially coincident. Controllable welding means and controllable cutting means are coupled to the side beam and are capable of linear translation therealong. Controllable drive means is provided for: rotating the headstocks so that the cylindrical workpiece secured thereto is caused to rotate about its longitudinal axis; causing the welding means to translate along the side beam; and causing the cutting means to translate along the side beam. Control means is provided for controlling the drive means and for: activating the welding means into welding operation; activating the cutting means into cutting operation; and, for coordinating the control function to weld a plurality of the cylindrical workpieces together in end-to-end manner and to then cut a plurality of openings in the welded together workpieces with the welding locations and the openings being substantially precisely located in a predetermined reproducible manner.
