== Abstract ==

Research on ultrasonic welding of composites has focused mostly on studying
parameters that are inputs for the process or material-related parameters, but almost no attention
has been given on the effect of manufacturing tolerances. In this work, we investigated how an
angle between adherends impacts the welding process and the weld quality. By increasing the
angle between top and bottom adherends, it was found that the duration of the process increased
while the power consumed, the weld uniformity and the weld strength decreased. However, by
increasing the clamping distance, which increased the compliance of the adherends and hence
their ability to deform under the applied welding force, the effect of the misalignment on both
the welding process and weld quality could be substantially reduced.
