1.0 PURPOSE

The 704th Test Group’s (704 TG) mission is to be the premier provider of unique test and evaluation capabilities relevant to tomorrow’s warfighter through world-class people improving technical excellence, cost-effectiveness, and agility. The 846th Test Squadron (846 TS) is one of the units assigned as part of the 704 TG. The 846 TS’s primary test capability is the Holloman High Speed Test Track (HHSTT) where they utilize rocket powered sled trains to simulate flight like environments and scenarios with the control and recovery of a ground-based system.

The 846 TS requires a new bed fixture plate large enough and weighing enough to control the stresses generated in the manufacturing process. This type of bed fixture plate is used by multiple industries to manufacture large, welded structures. Large, welded structures or “weldments” undergo stress movements as the metal is heated and cooled in the welding process which can cause the final weldment to be out of dimensional tolerance. The mass and materials of this type of bed fixture plate is vital for controlling the structural stress generated by welding processes and is usually 2.5 time the mass of the weldment.
