Abstract : Equipment was assembled for ultrasonic welding with power-force programming, to provide incremental changes in ultrasonic power and clamping force during a single weld interval. Preliminary welding of 2024-T3 aluminum alloy and Inconel X-750 showed significant weld strength improvement with power-force programming, which was selected without extensive experimentation. Significantly improved weld strengths and lower strength variability were obtained with powerforce programmed welding of 0.010-in. and 0.013-in. molybdenum-0.5% titanium alloy and with 0.015-in. B-66 niobium alloy.
