Abstract:

Investigations with thin gages of molybdenum-0.5 titanium alloy, niobium-10 titanium-10 molybdenum alloy, and tungsten showed that these materials are susceptible to ultrasonic welding, and that the strength decay of such ultrasonic welds at 2000 F is not appreciably greater than that of the parent sheet material. Weld cracking tendencies in some instances were attributed primarily to material contamination and in other instances to non- uniform material quality. It was postulated that improved weld quality can be obtained by strict control of material quality and by the use of programmed ultrasonic power and clamping force.
