About this work
A technician is pictured at the Marshall Space Flight Center welding the Y-ring to the S-IC stage bulkhead and the fuel tank for the Saturn V SA-502 launch vehicle (Apollo 6 mission) in building 4705. The size of the S-IC required a special rig known as the Y-ring to join the tank wall cylinders and domes together. The Y-ring was designed to eliminate lap joints where the tank domes, wall, and adjoining structure (such as the intertank segment) came together.
