Space Shuttle ET Friction Stir Weld Machines

摘要

The first flight-qualified hardware was welded at the close of 2002. The FSW program originally called for an additional machine to be used to either weld the opposite side (root) of each weld or to be available to perform repair passes as required. Part way through the design and review process for these machines, NASA was sufficiently confident that this equipment would produce sound welds from one side that the additional weld station was eliminated. Implementation of the FSW process into ET production is a successful Shuttle Upgrade Program. This technology and equipment will make the shuttle program safer and more affordable. FSW of the Space Shuttle ET will be one of the most visible and publicized applications of the process, and General Tool is proud to have been a part of it. Finally, NASA was so pleased with the innovative features of these tools that Ron Dittemore, Space Shuttle Program Manager, presented the "Space Shuttle Program STAR Award" to the author in May of 2003.
