Abstract:
1. A method for forming a flow nozzle having a plurality of fluid-tight adjacent chambers, using a plurality of L-shaped channels each having a linking member and a radial member, the method comprising: welding each linking member to an adjacent L-shaped channel, operatively forming a linking member contiguous surface; orienting each radial member substantially perpendicular to a first side of the contiguous surface; forming a second side of the contiguous surface into a flow nozzle wall; shaping a jacket operable to contact each of the radial members when the jacket is oriented substantially parallel to the contiguous surface and separated from the contiguous surface by each of the radial members; and welding the jacket to each radial member to operably form the plurality of fluid-tight adjacent chambers bounded between adjacent ones of the radial members, the jacket, and the contiguous surface.
