Abstract:

The effect of input power, clamping force, and duration of welding interval on the tensile-shear strength of ultrasonic welds in 0.005-in. Mo-0.5 Ti alloy sheet were studied and the results are tabulated. Exploratory tensile- shear measurements were made in 0.010-in. Mo-0.5 Ti alloy sheets welded with 1800 w applied for 0.6 sec and clamping force levels of 400 and 350 lb. No correlation between weld strength and clamping force was obtained for 0.005-in. W sheets welded at 1600 w, a weld interval of 0.3 sec, and clamping forces from 300 to 900 lb. The effects of etching and degreasing of 0.005-in. D-31 alloy prior to welding were compared.
