A versatile full vehicle test facility incorporating electro-hydraulic excitation and novel facility design offers great potential for useful testing. Facility description, application, and results produced are discussed and illustrated. Much development effort went into the evolution of the test equipment which was designed to meet objectives of both durability and vibrational measurements. Advantages of pit installation for the seismic mass and power room are aspects of the physical setup contributing efficiency and cleanliness. Programming techniques used to obtain good results with the equipment include magnetic tape profiles of durability courses as well as function generators and the system master program panel.

NEW WELDING processes are dropping costs while providing improvements in weld quality. This paper describes some of the more promising new developments in pressure and fusion welding and brazing. Included in the discussion are ultrasonic, high frequency resistance, foil seam, magnetic force, percussion, friction, and thermopressure welding and diffusion bonding. The description of adhesive bonding includes the development of glass or ceramic materials as structural adhesives.*
