ABSTRACT:
Successively laser cutting configurated openings in the walls of tubular manifold members with a plurality of robots and cooperative fixtures circumferentially around a cutting laser focus, the robots sequentially gripping the tubular members secured in exact orientation and position in the respective fixtures, by circumferentially expansible gripping jaws inside the tubular members, and advancing the members to and through a 360 degree pattern about the laser focus. The manifold laterals are subsequently welded to the member around the laser cut openings.
