ABSTRACT:
An apparatus for welding T-frame stiffeners circumferentially to the interior surface of a cylindrical shell at selected axial positions to fabricate reinforced hull sections suitable for boat construction is disclosed. The apparatus is adapted for providing simultaneous two-sided Tee welds of the T-frame to the shell using radiation from a laser source to form quickly the welds which significantly reduces the time and costs of fabricating hull subassemblies.
